Soldering heat: some treated product may have substantial resis- tance change during soldering operation. It is recommended that parts be tested to evaluate soldering heat effects. 1-866-9-OHMITE Intl 1-847-258-0300 Fax 1-847-574-7522 www.ohmite.com info ohmite.com 33 Temperature rise, C Temperature C Percent Rated Power
