TT ELECTRONICS / WELWYN W22 Series Wirewound Resistor - 3W

The TT ELECTRONICS / WELWYN W22 Series is a high-performance wirewound resistor engineered for demanding applications requiring stability and durability under high-temperature conditions. This robust component is built using a precision wirewound construction, offering a reliable and consistent 1.2 kohm resistance with a ±5% tolerance. Its design is focused on managing significant power dissipation, making it an essential part of power supply circuits, motor controls, and industrial electronic systems where heat generation is a critical factor.

Constructed with an axial leaded package, the resistor is designed for straightforward through-hole PCB mounting, providing strong mechanical stability and excellent solderability. The high-power rating ensures it can handle substantial electrical loads without compromising performance, supported by a voltage rating of 200V. Its exceptional operational temperature range, from -55°C to +350°C, allows it to function reliably in extreme environments, from freezing industrial settings to high-heat engine compartments.

Key to its performance is a low temperature coefficient of ±75 ppm/°C, which minimises resistance drift due to thermal changes, ensuring circuit accuracy and stability over time. The rugged wirewound technology provides superior overload handling and surge protection compared to standard film resistors. This component is free from Substances of Very High Concern (SVHC) as of the latest assessment, aligning with modern environmental and safety standards.

Ideal for engineers and technicians, this resistor is a cornerstone for building robust, long-lasting electronic assemblies where precision, power handling, and thermal resilience are non-negotiable requirements.
