Rated voltage = Power rating x resistance value or max. working voltage, whichever is lower.
* For resistors operated in ambient temperature over +70°C, power rating shall be derated like shown in „DERATING CURVE“.
** Please contact KOA about the increased max. working voltage and the max. overload voltage.
Care should be taken, that RK73B1F may be damaged when static electricity occurs and is applied in the equipment assembly process.
