TT Electronics / Welwyn W23 Series 150 Ohm 10W Wirewound Resistor

The TT Electronics / Welwyn W23 Series wirewound resistor is a robust and reliable axial-leaded component designed for demanding applications where stability and power handling are critical. Featuring a resistance of 150 ohms and a high power rating of 9W, this resistor is engineered to manage significant electrical loads while maintaining consistent performance.

Constructed using precise wirewound technology, it offers excellent resistance tolerance of ±5% and a low temperature coefficient of ±75ppm/°C. This ensures minimal variation in resistance value across a wide operational temperature range from -55°C to an impressive maximum of 350°C. The component is also rated for up to 500V, making it suitable for higher voltage circuits.

With its durable axial leaded package, it is easy to mount on printed circuit boards or into point-to-point wiring setups. The W23 Series is known for its high-quality construction and long-term reliability, making it a trusted choice for power supply design, motor controls, industrial equipment, and other electronic systems requiring precise current limiting or voltage division.

Its compact dimensions (15mm depth, 33mm width, 43mm height) and low weight of 3.5 grams allow for efficient use of space on boards and in assemblies without compromising on thermal or electrical performance.
