washer resistorResistor Washers are available in a wide variety of diameters to meet your application needs. The washers are utilized for capacitor charge and discharge, crowbar, impulse duty areas, electrical transmission, AC/DC motor drives, and dynamic breaking systems. These ceramic composition resistors perform well where high peak power or high energy pulses are required to be handled. These non-inductive resistors are able to dissipate the energy uniformly through the entire resistor body. They can be stacked together, forming a large resistor assembly, to dissipate large amounts of energy.

Part Number plus the Resistance Code is used for specifying a particular part. The Resistance code is defined by the first two numbers of the resistance value, followed by a single number multiplier, and the resistance tolerance (20% is L, 10% is K, 5% is J). When the resistance is less than 10 ohms, the multiplier is not used and replaced by an "R".

For example, a 3.50" x 0.780 X 0.5" Ceramic Resistor Washer at 100 ohms +/-10% would be qualified as "83-DEA-101K, and a 4.38" x 0.78" X 1.0" Ceramic Resistor Washer at 2.5 ohms +/-20% is 83-WFBW-2R5L.
