TT ELECTRONICS / WELWYN - W21 Series Wirewound Resistor 5% 10 Ohm - 14W
TT ELECTRONICS 3W wirewound resistor, 10 Ohm ±5%, axial leaded. For power supplies, motor controls & industrial applications. Wide -55°C to 350°C range.
The TT ELECTRONICS / WELWYN W21 Series Wirewound Resistor is a robust and reliable axial-leaded component designed for a wide range of electronic applications. Engineered with precision, this 10 Ohm resistor offers excellent stability and durability, making it a trusted choice for engineers and hobbyists alike. Its construction utilises high-quality wirewound technology, ensuring consistent performance even under demanding electrical loads and thermal conditions.
With a substantial power rating of 3 Watts, this resistor is capable of handling higher power dissipation than standard resistors, making it suitable for power supply circuits, motor controls, and other applications where energy management is critical. The resistance tolerance of ±5% provides a good balance between precision and cost-effectiveness for general-purpose use. The component is rated for up to 100 volts, offering a solid safety margin for many low to medium voltage circuits.
Performance is maintained across a broad temperature spectrum, from a frigid -55°C to an extreme 350°C, thanks to its stable wirewound construction and a temperature coefficient of ±75ppm/°C. This thermal resilience ensures reliable operation in environments subject to temperature fluctuations, such as in industrial controls, automotive electronics, and heating appliances. The axial leaded package, with its industry-standard form factor, facilitates easy installation and secure mounting on printed circuit boards (PCBs) or terminal strips.
