Product Information

Product Overview

  • The Welwyn RC55 series are axial leaded, precision metal film resistors. The resistance value includes E24 and E96 decade values from 1ohm to 4Mohm. These resistors have a metal film deposited on high quality ceramic former. Nickel plated steel caps are force fitted to the former and termination wires are welded to the caps. The resistor is adjusted to value by a helical cut in the film and the body is protected with a specially formulated epoxy coating.

    • Available in ±0.055(W), ±0.1%(B), ±0.25%(C), ±0.5%(D) & ±1%(F) tolerance values
    • Temperature coefficient is 5(V), 10(T), 15(Y), 25(D), 50(C) & 100ppm/°C(Z) values available
    • Power rating of 0.25W
    • Limiting element voltage of 350V
    • Low noise and negligible voltage coefficient
    • Operating temperature ranges from -55°C to +155°C
