    • Non RoHS Thin Film Fuse Obsoletion

      PCN# EFU100-3 Littelfuse Inc. would like to inform customers that it will cease production of its Non-RoHS compliant and lead based Surface Mount Thin Film Fuses products on December 31 2008. The product series impacted are the following. Thin Film Fuse Series - 0430, 0433, 0434 and the 0429xxx.WRM series. The final date for which orders will be taken is September 30, 2008. In all cases Littelfuse has RoHS and Lead-Free alternative series now available . The most up to date information on these series can be found on the Littelfuse website, http://www.littelfuse.com/. Littelfuse Inc is implementing this change so that it can continue to pursue a policy of manufacturing and selling "Green" products.
