Description Vishay Sfernice 25W RCH25 series resistors suitable for RCH 25 W chassis series are designed to be mounted on heat sinks. Can withstand high short-term overload with thick coating and non inductive low heat radiation. Installation is the same as RH wire wound resistors, especially suitable for high-frequency operation and circuit cutting.

The main feature table is only applicable to resistors appropriately installed on heat sinks, with a thermal resistance of 1 ° C/W at rated powers of 25 and 50W, 0.7 ° C/W at rated power of 100W, and 0.28 ° C/W at rated power of 250W. This data is only valid when hot oil grease is used and the resistor is correctly tightened by the mounting screw. Tightening torque - RCH25 | RCH50 | BDS100 | BDS250 0.7Nm | 1Nm | 2Nm | 2Nm
