    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.

    Ward Leonard 250, 4000, 500 Ohm Multi-tapped Ceramic Wirewound Resistor, 55 Watt.

    Elliptical shaped resistors increase the radiating surface and provides a core considerably stronger than an ordinary flat rectangular base, and insures that the wire lies flat against the entire winding surface. These reistorscan also be stacked.

    Stripohm resistors are equipped with metal strip (Spring ClipType) mounting brackets.

    Multi-Tapped, 250, 4000, 500 Ohms

    Resistance: 4750 Ohms Total, tapped 500 ohms from one end and 250 ohms from the opposite end.

    Power: 55 Watts

    Body Size Approximately 3.5 inches long and 1 inch wide.

    Mounting centers 4.25 inches with 0.375 inch integral stand-offs.
