Vitreous Wirewound Resistors with Lugs

The GWS series, with completely welded construction, is

the perfect choice for high continuous power dissipation up

to 500 W with the option for adjustable (GWS E) and

non-inductive (GWS Ni) types. The components of this

series are well suited for harsh environments and exhibit a

long lifetime. With their high pulse power capability, they are

the ideal choice as inrush current limiters. Typical

applications include but are not limited to drive systems,

power supplies, frequency inverters, AC and DC filters, and

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.

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

APPLICATIONS

• Inrush current limiter

• Capacitor charge / discharge

• Snubber resistor

• Brake resistor

• Filter resistor
