Resistance Example: R075 = 75m 7R50 = 7.5 75R0 = 75 7K50 = 7500 Tolerance RoHS F = 1% Compliant G= 2% J = 5% Maximum base plate temperature of the resistor must be monitored and kept within specified limits to establish the power rating. Best technique is to attach a thermocouple to the side of the base plate of the resistor. Temperature of plastic housing or heat sink cannot be used to establish rating of the resistor. 1-866-9-OHMITE * Int'l 1-847-258-0300 * Fax 1-847-574-7522 * www.ohmite.com * info@ohmite.com
