TT ELECTRONICS / WELWYN RC Series Metal Film Resistor 634R 0.25W

The TT ELECTRONICS / WELWYN RC Series Metal Film Resistor offers high precision and reliability for demanding electronic applications. With a tight resistance tolerance of ±0.1% and an extremely low temperature coefficient of ±15ppm/°C, it ensures stable performance across a wide temperature range from -55°C to 155°C.

Featuring a power rating of 0.25W (250mW) and a voltage rating of 200V, this axial leaded component is designed for general-purpose and precision circuitry where consistent values are critical. The metal film construction provides excellent long-term stability and low noise, making it a preferred choice for audio equipment, measurement instruments, and signal processing circuits.

Key Features

• High Precision: The 0.1% tolerance guarantees accurate resistance values for critical circuit design.
• Exceptional Stability: A low temperature coefficient minimises resistance drift with temperature changes, ensuring consistent operation.
• Robust Construction: Metal film technology offers superior performance compared to carbon film, with better stability and lower noise.
• Wide Operating Range: Functions reliably in environments from -55°C to 155°C, suitable for both industrial and commercial applications.
• Axial Leaded Package: The traditional through-hole design facilitates easy mounting and soldering onto printed circuit boards (PCBs).

This component is an essential part of any engineer's or hobbyist's toolkit for building reliable amplifiers, filters, voltage dividers, and other analogue or digital circuits where precision is paramount.
