Cautions Solderability: may be affected due to oxidization of lead wire Resistance value: some units may not completely recover to original value. Soldering heat: some treated product may have substantial resistance change during soldering operation. It is recommended that parts be tested to evaluate soldering heat effects. 1-866-9-OHMITE • Int’l 1-847-258-0300 • Fax 1-847-574-7522 • www.ohmite.com • info@ohmite.com 33 Surface Mount Power d im e nsions (in./mm) M L B A N P J E Note 2 K =0.006 Ref.
