TT Electronics Welwyn W22 Series Wirewound Power Resistor, 1.5Ω - 7W

The TT Electronics Welwyn W22 Series Wirewound Power Resistor is a robust and reliable component designed for demanding electronic applications requiring stable performance under power. These resistors utilise a classic wirewound construction, providing excellent power handling and long-term stability in a compact, axial leaded package. They are an ideal choice for power supply circuits, motor controls, braking systems, and any application where a durable, high-wattage resistor is essential.

Constructed to exacting standards, this resistor series offers a generous power rating and can operate across an extremely wide temperature range, from severe cold to intense heat. This makes it suitable for industrial environments, automotive electronics, and professional audio equipment where consistent performance is critical. The precision wirewound technology ensures a low temperature coefficient, meaning the resistance value remains stable even as the component's temperature changes during use.

Key Features & Benefits

• High Power Handling: Designed to dissipate significant thermal energy, making it perfect for current-limiting and load-sharing duties.
• Wide Operating Temperature: Reliable performance from -55°C to +350°C ensures suitability for harsh and variable environments.
• Stable Performance: A low temperature coefficient (±75ppm/°C) provides consistent resistance values, contributing to circuit accuracy and reliability.
• Durable Construction: The wirewound element and robust casing offer excellent mechanical strength and resilience against vibration.
• Axial Leaded Design: The traditional through-hole format allows for secure mounting on printed circuit boards (PCBs) using standard soldering techniques, facilitating easy integration into existing designs.

With its combination of a precise 1.5-ohm resistance, a 5% tolerance, and a high voltage rating, the W22 Series a
