TT ELECTRONICS / WELWYN - Wirewound Resistor 5% 5 Ohm, W22 Series - 7W

Engineered for robust and stable performance in demanding electronic circuits, the TT ELECTRONICS / WELWYN Wirewound Resistor from the W22 Series is a high-power, precision component. Its core technology utilises a wirewound construction, which provides excellent load-bearing capability and long-term reliability under high-temperature conditions, making it ideal for power supply, control, and industrial applications.

This resistor is designed to handle significant power dissipation with a rating of 6W, ensuring stable operation even in high-current scenarios. It features a precise resistance value of 5 ohms with a tight tolerance of ±5%, guaranteeing consistent performance across all units. The component is housed in a durable axial-leaded package, facilitating easy mounting and soldering onto printed circuit boards (PCBs) or into point-to-point wiring assemblies.

Key Specifications & Performance

The resistor boasts an impressive operating temperature range from -55°C to +350°C, allowing it to function reliably in extreme environments, from freezer controls to high-temperature industrial machinery. It has a low temperature coefficient of ±75ppm/°C, which minimises resistance drift with temperature changes, a critical factor for precision circuits. Furthermore, it is rated for voltages up to 200V, providing a safe margin for various electronic designs.

Constructed from high-quality materials, this component is built to last. Its wirewound design ensures superior surge handling and stability compared to other resistor types. The W22 Series is known for its ruggedness and is a trusted choice for engineers requiring dependable power resistors for amplifiers, braking systems, and power conversion units.
