Vishay RPS500 Series Aluminium Housed Screw Termination Thick Film High Power Resistor, 2.5Ω ±5% 500W
Vishay
Thick film power resistors 250 W and 500 W Vishay Sfernice RPS series thick film non-inductive resistors for heatsink mountingParticularly suited to severe impulse applicationsEasy mounting and optimised housing cut-outsLow thermal radiation Power Dissipation 70°C on radiators: RPS 250DH: 250W RPS 500DH: 500W Tolerance: ±5% Temperature coefficient: ±250 ppm/°C (R ±150 ppm/°C (R1 Ω) Max. service voltage: 5 kV RMS Thermal resistance: RPS 250DH: 0.22°C/W RPS 500DH: 0.11°C/W Dielectric rigidity: 14 kV RMS Operating temperature: –55°C to +125°C Non-Inductive - Panel Mount Non-Inductive - Heatsink Mountable Virtually non-inductive, thick film power resistors designed for direct heatsink attachment and ideal for installation where easy connection in a limited space is required.A specially formulated cermet film is deposited onto a high purity alumina substrate and housed in a hard epoxy moulding into which the terminals are integrated.Values of 1Ω and below have 4 terminals to permit voltage sensing; all other values have 2 terminalsApplications include circuits where low inductance, high frequencies and pulse overloads are key parameters.Application note: derate linearly from full power at 25°C for 25 and 50W types and 70°C for 100 and 250W types to zero at 125°C. For best heat transfer it is suggested that a heat compound is applied between the alumina bottom surface and the heatsink chassis/surface. Key Characteristics Overload duration RCH25 RCH50 BDS100 BDS250 1 sec. 375W 750W 200W 1500W 2 sec. 300W 600W 150W 1250W 5 sec. 125W 250W 125W 1000W 10 sec. 75W 150W 100W 750W For each degree the ambient temperature is raised above 25°C, there is a reduction by 1% of the permitted overload.The key characteristics table is only applicable to resistors suitably mounted on a heatsink with a thermal resistance of 1°C/W for 25 and 50W ratings, 0.7°C/W for 100W and 0.28°C/W for 250W ratings.This data is only valid when thermal grease is used and the resistor is correctly tightened by mounting screws.
