F55J25RE

The F55 series from Ohmite are 250 type 'Thin' Stackohm® vitreous enamel power resistors. The Ohmite’s “thin” stackable 250 Type resistors is considered where there is a space constraint. These oval-shaped ceramic-core resistors feature a low profile to permit installation in spaces with height restrictions. 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. Durable 250 Type resistors are fully welded and coated with lead free vitreous enamel.
