Ohmite WLBR025FE Miniature Wirewound Current Sense Resistor
The OHMITE WLBR025FE is a miniature wirewound current sense resistor specifically engineered for applications requiring precise current monitoring and control. Constructed with a CeramTec Rubalit 96% alumina ceramic core and encapsulated in SUMICON 1200 epoxy, this resistor offers exceptional stability and reliability. The CN49W alloy resistance wire ensures a temperature coefficient of ±20ppm/°C, contributing to accurate measurements across varying temperatures. Its miniaturized dimensions and robust power-to-dimension ratio make it ideal for space-constrained environments in industrial automation, power supplies, and motor control systems. Manufacturing utilizes CNC machine tools to ensure consistent product quality, and the lead-free copper wire construction aligns with modern environmental standards.
