    OHMITE - RWO55AW250 - Resistor, Ceramic. 250 Ohm 55W Adjustable Wirewound

    When limited space is a consideration, choose Ohmite’s “thin” stackable Type resistors. 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.

    Status: Discontinued

    Resistance: 250 Ohm.

    Power: 55 watt.

    Tolerance: 10%.

    Adjustable.

    Technology: Wirewound.

    Enamel Coated.

    Dimensions: Overall 4.386" long x 1.061" deep x 0.479" high.
