TT Electronics Welwyn RC Series 0.25W 7.87kΩ Metal Film Resistor 0.1%

The TT Electronics Welwyn RC Series 0.25W Metal Film Resistor delivers exceptional accuracy and stability for critical electronic circuits. With a precise resistance value of 7.87 kΩ and a very tight tolerance of ± 0.1%, this component is engineered for applications where performance and reliability cannot be compromised. The metal film construction provides superior characteristics compared to carbon film, offering low noise, excellent long-term stability, and a low temperature coefficient.

This axial-leaded resistor is rated for a power dissipation of 250 mW (0.25W) and can handle voltages up to 200V. Its operating temperature range is impressively broad, functioning reliably from -55°C to +155°C. The temperature coefficient is specified at a low ± 15 ppm/°C, meaning the resistance value changes very little with temperature fluctuations, which is crucial for precision analogue circuits, measurement equipment, and instrumentation.

The compact axial package is designed for easy mounting on printed circuit boards (PCBs) using traditional through-hole soldering techniques. Its robust construction ensures it can withstand the rigours of automated assembly processes and provides dependable service in the finished product. The TT Electronics Welwyn brand is synonymous with quality in passive components, making this resistor a trusted choice for engineers and technicians.

Ideal for use in: precision measurement devices, medical electronics, audio equipment, test and calibration instrumentation, communication systems, and any circuit requiring a stable, accurate resistance value over time and temperature.
