Resistor Washers
Resistor Washers are available in a wide variety of diameters to meet your application needs.
They are used in capacitor charge and discharge, crowbar, impulse-duty, electrical-transmission, AC/DC motor-drive, and dynamic-braking applications.
These ceramic-composition, non-inductive resistors perform well in applications that require high peak power or high-energy pulses. They dissipate energy uniformly throughout the resistor body.
Washers can be stacked to form a large resistor assembly for greater energy dissipation. Contact surfaces are available in aluminum or brass, and an anti-track coating is available on the outside and inside diameters between the contact surfaces.

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 3.60” x 0.80” X 0.5” Ceramic Resistor Washer at 100 ohms +/-10% would be qualified as “85-DEA-101K, and a 4.45” x 0.80” X 1.0” Ceramic Resistor Washer at 2.5 ohms +/-20% is 85-WFBW-2R5L.
