Power Resistor 2.2Ω 5W Through Hole

Power Resistor 2.2Ω 5W Through Hole

The Power Resistor 2.2 Ω 5 W (AX5W axial style) is a compact, high-dissipation through-hole resistor designed to handle steady power loads while maintaining a stable low resistance. Its cylindrical, axial-lead body provides a robust mechanical mount for printed circuit boards or chassis wiring, and the construction is optimized for even heat distribution to keep thermal stress low during continuous operation.

Internally the device uses a power-resistor element (commonly wire-wound or a ceramic resistance element) encapsulated in a flame-retardant, heat-resistant coating, giving the component both electrical reliability and safety under elevated temperatures. The axial leads are tinned for solderability and mechanical strength, easing assembly and rework in manual or automated soldering processes.

When deployed, this 2.2 Ω/5 W resistor provides predictable current limiting, voltage dropping, or load-simulation functions in power supplies, motor drives, and audio circuits. Its combination of low ohmic value, 5-watt dissipation capability, and standard through-hole format makes it a practical choice for engineers seeking a durable, easy-to-mount power resistor for moderate power applications.
