Dear Valued Customers of Bourns,

Bourns does not export gallium or germanium as a raw material from the People’s Republic of China (PRC) for the manufacture of Bourns® products.

We have initiated a survey of our supply chain and thus far have not identified any use of gallium or germanium by our supply chain from sources within the PRC.

If we discover any dependency of our supply chain on PRC sourced gallium and/or germanium, we will notify any customers who might be negatively impacted by such finding.

Sincerely,

BOURNS, INC.

James Harrington

Senior Vice President, Worldwide Sales
