Conflict Minerals Report
For the Year Ended December 31, 2020

    This Conflict Minerals Report (“Report”) of Littelfuse, Inc. and its consolidated subsidiaries (collectively, “Company,” “we” or “our”) for the year ended December 31, 2020 is filed in accordance with Rule 13p-1 under the Securities Exchange Act of 1934, as amended (the “Rule”). The Rule requires the disclosure of certain information if a registrant manufactures or contracts to manufacture products for which certain “Conflict Minerals” (as defined below) are necessary to the functionality or production of such products. Conflict Minerals are defined as (i) cassiterite, columbite-tantalite, gold, wolframite, or their derivatives, which are limited to tin, tantalum, tungsten, and gold, or (ii) any other mineral or its derivatives determined by the U.S. Secretary of State to be financing conflict in the Democratic Republic of the Congo or an adjoining country (collectively, the “Covered Countries”).

    The Company’s operations, including through its subsidiaries, may at times manufacture, or contract to manufacture, products for which Conflict Minerals are necessary to the functionality or production of those products. Littelfuse is a member of the Responsible Minerals Initiative (“RMI”), formerly the Conflict-Free Sourcing Initiative. We leverage our RMI membership to continue to monitor best practices related to our reasonable country of origin inquiry (“RCOI”) of the Conflict Minerals in our supply chain.

    This RCOI was reasonably designed to determine whether any of the Conflict Minerals originated from the Covered Countries and whether any of the Conflict Minerals may be from recycled or scrap sources. The results of our reasonable country of origin inquiry regarding the Conflict Minerals, as well as our additional due diligence regarding the sources of the Conflict Minerals, are contained in this Report.

    The report presented herein is not audited.

1.Company Overview

    Founded in 1927, Littelfuse, Inc. is a global manufacturer of leading technologies in circuit protection, power control and sensing. Serving over 100,000 end customers, the Company's products are found in automotive and commercial vehicles, industrial applications, data and telecommunications, medical devices, consumer electronics and appliances. With our broad product portfolio of fuses, semiconductors, polymers, ceramics, relays and sensors, and extensive global infrastructure, the Company's worldwide associates partner with our customers to design, manufacture and deliver innovative, high-quality solutions for a safer, greener and increasingly connected world.

    The Company’s reporting segments consist of Electronics, Automotive and Industrial, as described more fully in Part I, Item 1 of the Company’s annual report on Form 10-K for the year ended December 26, 2020. Such annual report is available free of charge through the Investor Relations section of the Company’s website at The information contained in the Company’s website is not incorporated by reference into this Report and should not be considered part of this Report.
Supply Chain

    The Company manufactures, or contracts for the manufacture of, a wide range of products that contain Conflict Minerals but we do not purchase ore or unrefined Conflict Minerals directly from mines, smelters or refiners and generally are many levels downstream from these market participants. For this reason, we rely on the information provided by our direct suppliers along with appropriate due diligence processes. Through the process described in this Report, we seek to ensure that our sourcing practices are consistent with our guiding principles on responsibly sourcing the Conflict Minerals and to encourage responsible minerals sourcing in our supply chain.

2.Reasonable Country of Origin Inquiry

    Our RCOI began with a review of all our materials suppliers that, due to the nature of their business, might utilize Conflict Minerals (referred to as “direct suppliers”). Direct suppliers were contacted to complete the Conflict Minerals Reporting Template (the “CMRT”). The CMRT is regarded as the most commonly accepted reporting tool for conflict minerals content and sourcing information worldwide. Upon request, suppliers were provided with training materials on how to complete the CMRT. The CMRT asked the suppliers, among other things, to disclose the origin of any Conflict Minerals used in their manufacturing processes and to identify the Conflict Minerals processing facilities within their supply chains.

    The Company obtained responses from 90% of our direct suppliers that were surveyed. Based on the survey responses obtained, we have reason to believe that some of the Conflict Minerals supplied to us may have originated in the Covered Countries, and we have reason to believe that certain of the Conflict Minerals came from recycled or scrap sources.

    Our RCOI process was reasonably designed and performed in good faith, however, there are inherent limitations in the information provided to us by third parties, including the possibility of information being inaccurate, incomplete or falsified despite our efforts to validate and confirm the information.

3.Due Diligence Process

    Summarized below is our due diligence process, the components of which conform to, in all material respects, the framework in the Third Edition of the Organization for Economic Co-operation and Development Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High- Risk Areas and related supplements for gold, tantalum, tin and tungsten.

a) Establish Company Management System

Maintained a Conflict Free Statement which provides that the Company expects its suppliers to continuously monitor both direct and indirect supply chains to avoid procurement of materials from Covered Countries, and to be forthright in sharing compliance information with the Company. We will show preference to suppliers that meet or exceed these requirements.

Communicated with our direct suppliers through the above-described RCOI.

Maintained conflict-free sourcing requirements in our purchase order terms and conditions, supplier quality manual, supplier selection policy or similar documents.

Maintained a supplier qualification or selection program and an ongoing supplier audit program that includes, among other compliance items, confirmation of the suppliers’ adherence to our conflict-free sourcing requirements.

Distributed our Supplier Code of Conduct to all direct material suppliers that, among other things, requires suppliers to have a policy regarding responsible sourcing of Conflict Minerals in the Covered Countries. Our regular communications with our suppliers also include links to or copies of the Supplier Code of Conduct.

b) Identify and Assess Supply Chain Risks

Surveyed all direct suppliers that potentially supplied Conflict Minerals to the Company to determine the products provided to the Company with Conflict Minerals.

Conducted the RCOI described above to identify the smelters and refiners that contribute Conflict Minerals to the Company’s products.

Reviewed and compared the smelters and refiners identified by direct suppliers against the list of smelter and refiner facilities that have received a “conflict free” designation through the Responsible Minerals Assurance Process (“RMAP”), formerly the Conflict-Free Smelter Program.

c) Design and Implement a Strategy to Respond to Identified Risk

Conducted follow-up with direct suppliers that did not respond to the survey.

Engaged a third-party provider to assist with providing validated information from suppliers that did not initially respond to the survey.

Collaborated with our direct suppliers to investigate any smelter that did not have a conflict free designation through the RMAP and was not in the process of recertifying for such designation.

d) Carry out Independent Third-Party Audit

The Company is a member of the Responsible Minerals Initiative. We rely on the information published by the RMI to confirm the existence and verify the conflict-free status of the smelters or refiners identified during our due diligence.

e) Report on Supply Chain Due Diligence

This Report is available on our website at In addition to this Report, our Conflict Free Statement is also available on our website at

4.Due Diligence Results

    We solicited 1,271 direct suppliers and received a response from 90% of them. There were 35% of our responding direct suppliers that indicated the material they supply contains Conflict Minerals.

    From the information provided to the Company by its direct suppliers, we identified 524 unique smelters or refiners in our supply chain. According to information provided by our suppliers, below is the status of the unique smelters that were identified:

Communication Suspended - Not Interested41%
In Communication122%
Outreach required448%
RMI Due Diligence Review - Unable to Proceed41%

The smelter or refiner statuses utilized by RMI are defined as follows:

"Conformant" means that the smelter has been independently assessed and found conformant with the relevant RMAP standard.

"Active" means that a smelter has engaged in the RMAP program but has not yet been determined to be conformant.

"Communication Suspended - Not Interested" means that the entity has strongly communicated a lack of interest in participation.

"In Communication" means that the entity is not yet Active but is in communication with RMAP and/or a member company.

"Non-Conformant" means that a smelter has been independently assessed and found non-conformant with the relevant RMAP standard.

"Outreach Required" means that outreach is needed by RMI member companies to contact entity and encourage their participation in the RMAP program.

"RMI Due Diligence Review - Unable to Proceed" means that the entity has not met the threshold for Due Diligence Vetting Process after a period of 6 months. Status may change if additional information is submitted.

    We continue to monitor and evaluate all our direct suppliers and the smelters and refiners they report with the goal to be 100% conflict free.

    The smelters or refiners participating in the RMI that provide Conflict Minerals that originated from the Covered Countries, as reported by our suppliers, are listed on Appendix A.

5.Future Risk Mitigation Efforts

    The Company has taken or intends to undertake the following additional steps during the next compliance period. These steps are intended to improve the due diligence conducted to further mitigate the risk that our Conflict Minerals benefit armed groups:

Continue to improve upon our acquisition integration process to enable our Conflicts Minerals working group to be more efficient and ensure practices are consistent throughout the Company.

Maintain our direct supplier engagement efforts and follow industry standards for 2021 outreach.

Enhance our direct supplier communication and escalation process and encourage non-validated smelters or refiners in their supply chain to pursue compliance with an independent conflict-free program, such as the RMAP.

Participate in training programs, best practice sharing and other compliance program improvement initiatives available through our RMI membership.

Continue to request information on the origin of cobalt in our products on the Cobalt Reporting Template published by RMI to help ensure that the cobalt in our supply chain is responsibly sourced. Together with some of our customers, we began a cobalt traceability initiative in 2019.
