    WARD LEONARD - RWO20S50 - 20S50 - Resistor, Ceramic.

    Stripohm resistors utilize a flat, oval-shaped, ceramic base on which the resistive conductor is wound, they are practically identical in construction with Vitrohm tubular resistors. The core or base has a smooth surface with no sharp edges. This design precaution is taken to guard against wire breakage during manufacture. The fact that the core is slightly elliptical shape that increases the radiating surface slightly and provides a core considerably stronger than an ordinary flat rectangular base, and insures that the wire lies flat against the entire winding surface. Stripohm resistors are equipped with metal strip (spring clip type) mounting brackets. Stripohm resistor can be chassis mounted or stacked.

    Resistance: 50 Ohm.

    Power: 20 Watt.

    Technology: Wirewound, Stripohm.

    Terminals: Solder Lugs

    Viteous Enamel Coated.

    Dimensions: Overall 2.632" Long x 0.868" Wide, including contacts x 0.343" High.
