Ohmite WLAR015FET Miniature Wirewound Current Sense
The OHMITE WLAR015FET is a miniature wirewound current sense resistor specifically engineered for applications requiring ultra-low ohmic values. Its construction utilizes a 96% alumina ceramic core, stainless steel end caps, and a copper wire winding with a CN49W alloy for precise temperature coefficient control. Encapsulated in SUMICON 1100/1200 epoxy molding compound, this resistor provides excellent electrical insulation and mechanical protection. The CNC manufacturing process ensures consistent product quality, making it suitable for demanding industrial applications such as current sensing in power supplies, motor drives, and battery management systems. Its miniaturized design and low inductance contribute to efficient circuit performance.
