      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 terminals
      Applications 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.

      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.
