Metal-clad winding resistor WD

This is a high-performance metal-clad wirewound resistor that complies with the requirements of MIL18546, IEC115, and RoHS, available in a series from 5W to 300W, offering a minimum resistance value of 0.01Ω. The WD series high-power wirewound resistors, molded with thermally conductive silicone resin in an aluminum case with excellent thermal conductivity, provide an outstanding balance between pulse power capacity and the volume of the resistor. They achieve the best stability, short-term overload characteristics, and reliability, cultivated through advanced design and a long history. The rated power ranges from 5W to 300W, with a resistance range from 0.01Ω in the low resistance area to 100kΩ in the high resistance area, an operating temperature range of -25°C to +250°C, a temperature coefficient of resistance of 60ppm/°C for resistances below 100Ω and 30ppm/°C for resistances above 100Ω, and a shelf life stability of 1% over 3 years, with short-term overload rated at power x 10 for 5 seconds. The insulation withstand voltage is 1.5kV for small products and 5kV for large products.
