Vishay FST225JCT Silicone Coated Wirewound Power Resistor

The Vishay FST225JCT silicone-coated wirewound power resistor provides 4.7 kΩ resistance with ±5% tolerance in a through-hole, fixed-power package designed for industrial power dissipation. The wirewound construction with a silicone coating offers durability and high stability under long continuous-load operation, suitable for current-limiting and voltage-dropping applications. Common uses include industrial power supplies, motor-control systems, automation panels, process-control equipment, test and measurement instruments, electrical distribution assemblies, and other OEM machinery requiring dependable resistance performance. This part supports long operational life in demanding environments and is intended for repair, retrofit projects, and new installations by OEMs, system integrators, and maintenance technicians needing a reliable, silicone-coated resistor in through-hole form.
