TT Electronics Welwyn RC55 Resistor 562kΩ 0.25W 0.1%

The TT Electronics Welwyn RC55 Series axial leaded precision metal film resistor offers exceptional reliability and accuracy for your electronic circuits. Designed with a metal film deposited on a high-quality ceramic former, this component ensures stable and consistent performance across a wide range of conditions. Nickel-plated steel caps are force-fitted to the former, with termination wires securely welded to the caps for robust mechanical and electrical integrity.

The resistor is precisely adjusted to its target value using a helical cut in the film, and the body is protected by a specially formulated epoxy coating. This construction provides low noise performance and a negligible voltage coefficient, making it highly suitable for demanding applications where precision is paramount.
