Category: resistanceDescription: RCH 25 W The Vishay Sfernice 25W RCH25 series resistors in the chassis series are designed to be installed 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. Rated power: | ------------------------------------------------------------------------------------------------------------------------------------------------------------------| S | Cannot provide Ø D screws 28 | 14 | 27.5 | 18.3 | 18.3 | 19.8 | 7.7 | 3.2 M3### Non inductive - Panel Installation # # # Non inductive - Heat sink can be mounted on almost non inductive, thick film power resistors, designed for direct connection of heat sinks, suitable for installation in locations that require easy connection in limited spaces. Specially formulated metal ceramic film is attached to high-purity alumina, with a hard epoxy molded shell and integrated terminals inside. Values less than or equal to 1 Ω have 4 wiring terminals, allowing voltage induction; All other values have 2 wiring terminals for applications including circuits with main parameters of low inductance, high frequency, and pulse overload. **Application Description: * * Linear decrease from full power to zero power at 125 ° C for 25 and 50W types at 25 ° C and 100 and 250W types at 70 ° C. To achieve optimal thermal conductivity, it is recommended to use thermal paste between the aluminum oxide bottom surface and the radiator frame/surface. Main feature - Overload duration| RCH25 | RCH50 | BDS100 | BDS250 1 s | 375W | 750W | 200W | 1500W 2 s | 300W | 600W | 150W | 1250W 5 s | 125W | 250W | 125W | 1000W 10 s | 75W | 150W | 100W | 750W For every one degree increase in ambient temperature above 25 ° C, the allowable overload is reduced by 1%. 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 pow7333 -
