GWK, GWK Ni www.vishay.com Vishay Draloric Vitreous Wirewound Resistors with Ferrules FEATURES Excellent pulse load capability Non inductive type (Ni) available Different caps options: - GDK style with different inner threads - GZK made from drawn brass, nickel plated Easy to change when mounted with spring clips click logo to get started DESIGN SUPPORT TOOLS Non-flammable and enhanced humidity protection Material categorization: for definitions of compliance Models please see www.vishay.com/doc 99912 Available The GWK series, with completely welded construction, is APPLICATIONS the perfect choice for high continuous power dissipation up Inrush current limiter to 260 W with the option for a non-inductive type (GWK Ni). The components of this series are well suited for harsh Capacitor charge / discharge environments and exhibit a long lifetime. With their high pulse power capabilities, they are an ideal choice for inrush Snubber resistor limiters. Typical applications include but are not limited to Brake resistor drive systems, power supplies, frequency inverters, AC and DC filters, and snubber resistors. Specific application Filter resistor requirements (ohmic value, rated power, peak voltage, pulse shape, pulse duration, termination style, and environmental conditions) can be submitted to Vishay for a recommendation of the most suitable product.
