TT Electronics / Welwyn RC Series Resistor, 0.25W 0.1% 16.9KΩ

The TT Electronics / Welwyn RC Series Resistor is a high-precision, metal film component designed for critical electronic applications requiring exceptional stability and accuracy. With a resistance value of 16.9kΩ and a tight tolerance of ±0.1%, this resistor ensures reliable and consistent performance in precision circuits.

Its 250mW (0.25W) power rating and 200V voltage rating make it suitable for a wide range of low to medium power applications. The component is constructed using advanced metal film technology, which provides superior performance characteristics compared to carbon film alternatives, including lower noise, better long-term stability, and a more favourable temperature coefficient.

The resistor features an axial leaded package, making it compatible with traditional through-hole PCB (printed circuit board) mounting techniques. It is engineered to operate reliably across an extensive temperature range from -55°C to +155°C, ensuring functionality in demanding environments. The low temperature coefficient of ±15ppm/°C minimises resistance drift with temperature changes, a critical factor in precision analogue and measurement equipment.
