GWS, GWS E, GWS Ni www.vishay.com Vishay Draloric Vitreous Wirewound Resistors with Lugs FEATURES Lugs with various termination styles suitable for soldering or bolt connection Excellent pulse load capability Adjustable type (E) available Non inductive type (Ni) available Non-flammable and enhanced humidity protection Material categorization: for definitions of compliance please see www.vishay.com/doc 99912 The GWS series, with completely welded construction, is the perfect choice for high continuous power dissipation up APPLICATIONS to 500 W with the option for adjustable (GWS E) and Inrush current limiter non-inductive (GWS Ni) types. The components of this series are well suited for harsh environments and exhibit a Capacitor charge / discharge long lifetime. With their high pulse power capability, they are Snubber resistor the ideal choice as inrush current limiters. Typical Brake resistor applications include but are not limited to drive systems, power supplies, frequency inverters, AC and DC filters, and Filter resistor snubber resistors. For a given application, requirements of ohmic value, rated power, peak voltage, pulse shape, pulse duration, termination style, and environmental conditions may be submitted to recommend the most suitable product.
