Welwyn RC55 Precision Metal Film Resistor, 95.3Ω, 0.25W, ±0.1%

The Welwyn RC55 Series Precision Metal Film Resistor is an axial-leaded component designed for applications demanding high accuracy and stability. Featuring a resistance of 95.3Ω and a tight tolerance of ±0.1%, it provides reliable and consistent performance in precision circuits.

Constructed with a metal film deposited onto a high-quality ceramic former, the resistor ensures excellent long-term stability. Nickel-plated steel caps are force-fitted to the former, and termination wires are welded to the caps for robust electrical and mechanical connections. The resistance value is precisely adjusted via a helical cut in the film, and the entire body is protected by a specially formulated epoxy coating, offering enhanced durability and environmental protection.

With a power rating of 0.25W (250mW) and a limiting element voltage of 350V, this resistor is suitable for a wide range of electronic designs. It exhibits low noise and a negligible voltage coefficient, making it ideal for sensitive analogue and measurement equipment. The component operates reliably across an extensive temperature range from -55°C to +155°C.
