Flat/Oval Wirewound Resistors

Flat Wirewound Resistors, Industrial Power, Oval

By using oval-shaped ceramic-core, it will be helpful for saving the space of height, they are also equipped with integral mounting brackets so they can be fastened to a chassis and stacked in locations with limited surface area. When properly fastened, the mounting brackets add a heat sinking benefit resulting in a smaller size per watt. FWR flat resistors are fully welded and coated with lead free non-flammable resin.

Construction:

• (FWR) resistor is a flat tubular ceramic rod has two terminals and is wirewound with either copper wire or chromium alloy wire as a resistance element.
• Mainly utilized for industrial installations where height is limited. Features excellent windings, taps adding, low impedance, and PC board insertable.
