TT Electronics Welwyn RC55 Precision Metal Film Resistor 909kΩ 0.25W 0.1% Axial

The TT Electronics / Welwyn RC55 series precision metal film resistor offers exceptional accuracy and stability for demanding applications. With a resistance value of 909kΩ and a tight tolerance of ±0.1%, this axial leaded component ensures reliable performance in precision circuits.

Constructed with a metal film deposited on a high-quality ceramic former, the resistor features nickel-plated steel caps force-fitted to the former, with termination wires welded to the caps for robust connections. A helical cut in the film adjusts the resistance value precisely, and the body is protected by a specially formulated epoxy coating for durability.

Key Features:

• Power Rating: 0.25W (250mW)
• Resistance Tolerance: ±0.1%
• Temperature Coefficient: ±15ppm/°C
• Limiting Element Voltage: 350V
• Operating Temperature Range: -55°C to +155°C
• Low Noise: Negligible voltage coefficient for clean signal handling
• Package: Axial leaded, suitable for through-hole mounting

The resistor is available in E24 and E96 decade values from 1Ω to 4MΩ, making it versatile for various circuit designs. Its precision and reliability make it an excellent choice for measurement equipment, instrumentation, and other applications requiring high accuracy.
