Welwyn RC55 Precision Metal Film Resistor, 0.25W, 1MΩ, ±0.1%

The Welwyn RC55 series are axial leaded, precision metal film resistors, offering a resistance range from 1ohm to 4Mohm with E24 and E96 decade values. This particular model features a resistance of 1Mohm (1MΩ) with a tight ±0.1% tolerance, ensuring high accuracy for your electronic applications.

Each resistor is constructed with a metal film deposited on a high-quality ceramic former, with nickel-plated steel caps force-fitted to the former. Termination wires are welded to the caps for reliable connections. The resistive element is precisely adjusted via a helical cut, and the body is protected with a specially formulated epoxy coating, ensuring durability and stable performance.

With a power rating of 0.25W (250mW) and a limiting element voltage of 350V, this resistor is suitable for a wide range of precision circuits. It features low noise and negligible voltage coefficient, making it ideal for signal processing and measurement equipment. The operating temperature range spans from -55°C to +155°C, providing reliable operation in demanding environments.
