TT Electronics Welwyn RC Series Resistor 143kOhm 0.25W 0.1%

The TT Electronics / Welwyn RC Series Resistor is a high-precision metal film resistor designed for demanding electronic circuits that require stable and accurate performance. With a resistance of 143kΩ, a tight tolerance of ±0.1%, and a power rating of 250mW (0.25W), this axial leaded component delivers reliable operation in a wide range of applications.

Engineered with metal film technology, the resistor offers excellent temperature stability, characterised by a low temperature coefficient of ±15ppm/°C. This ensures minimal resistance variation across a broad operating temperature range from -55°C to 155°C. The component is rated for a maximum voltage of 200V, making it suitable for signal conditioning, voltage dividers, and feedback networks in precision circuits.

This through-hole resistor comes in a standard axial leaded package, which is easy to handle and solder onto printed circuit boards. Its compact, cylindrical body is lightweight and durable, ensuring long-term reliability in both prototyping and production environments.

Whether you are working on industrial control systems, test equipment, or audio electronics, this resistor provides consistent electrical characteristics and robust performance. The RoHS-compliant construction and SVHC-free status make it an environmentally conscious choice for modern electronic assemblies.
