TT Electronics Welwyn RC55 Precision Resistor 56.2ohm 0.25W 0.1%

The TT Electronics Welwyn RC55 Series precision metal film resistor offers reliable and accurate performance for demanding electronic circuits. Constructed with a high-quality metal film deposited onto a premium ceramic former, this axial leaded resistor ensures excellent stability, low noise, and long-term durability.

Nickel-plated steel caps are force-fitted to the former, with termination wires securely welded to the caps to provide robust connections. The resistance value is precisely adjusted using a helical cut in the film, and the component body is protected by a specially formulated epoxy coating, safeguarding the internal structure against environmental factors and mechanical stress.

Featuring a resistance of 56.2 ohms, a power rating of 0.25W, and a tight tolerance of ±0.1%, this component is engineered for high-precision applications. It boasts a low noise output and a negligible voltage coefficient, making it suitable for sensitive analogue and digital circuits. The resistor operates effectively within a wide temperature range of -55°C to +155°C, with a temperature coefficient of ±15ppm/°C ensuring minimal drift.
