*1: Use it on the condition that the case temperature is below the upper category temperature.
*2: Please contact us when resistors of irregular series are needed.
・ Rated Continuous Working Voltage (RCWV) shall be determined from RCWV=√Power Rating × Resistance Value.
・ Overload Test Voltage (OTV) shall be determined from OTV=Specified Magnification (refer to performance) × RCW.
Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use.
Should a safety concern arise regarding this product, please be sure to contact us immediately.
