IRF500, high-power wire-wound resistor is a type of resistor designed to handle relatively large amounts of power and dissipate it in the form of heat. These resistors are constructed using a resistance wire that is wound around a ceramic or metal core, providing the necessary resistance value and power handling capabilities.

Features and Applications:

Non-inductive, flat shaped aluminum housed wire wound fixed resistors with 50W to 500W.. Minimum resistance of 1ohm, +/-0.5% tolerance available. 10mm thickness allows excellent heat extrusion from resistor. Narrower body (IRN) will be suitable for high density installation. Light weight silicone filled insulation and higher temperature operating cement filled insulation are prepared. Strong over load characteristics are fit for applications of industrial power electronics, switching power supplies, braking resistors for motor control electronics, rush current protection in automotive electronics, industrial power supplies.
