Model RPS0250DH10R0JBZA3
Description 250 W The 500 W Vishay Sfernice RPS series thick film non inductive resistor is used for heat sink installation, especially suitable for harsh pulse applications. The shell opening is easy to install and optimize, and the low heat radiation is installed on the heat sink. Power consumption at 70 ° C: | RPS 250DH: 250W ------- | RPS 500DH: 500W Tolerance: | ± 5% Temperature coefficient: | ± 250 ppm/° C (R | ± 150 ppm/° C (R1 Ω) Maximum service voltage: | 5 kV Effective value Thermal resistance: | RPS 250DH: 0.22 ° C/W | RPS 500DH: 0.11 ° C/W Dielectric stiffness: | 14 kV Effective value Operating temperature: | -55 ° C to+125 ° C # # # Non inductive - Panel installation # # # Non inductive - Heat sink can be mounted on almost non inductive, thick film power resistor, designed for direct connection of heat sink, suitable for installation in positions that require easy connection in limited space. 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
