Maximum base plate temperature of the resistor must be monitored and kept within specified limits to es- tablish the power rating. Best technique is to attach a thermocouple to the side of the base plate of the resis- tor. Temperature of plastic housing or heat sink cannot be used to establish rating of the resistor. rev 12/19-1 1-866-9-OHMITE • Int’l 1-847-258-0300 • Fax 1-847-574-7522 • www.ohmite.com • info@ohmite.com 39
