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 marked with ( ).
Care should be taken, that RK73H1F may be damaged when static electricity occurs and is applied in the equipment assembly process.
