Ohmite WLAR030FE Miniature Wirewound Resistor
The OHMITE WLAR030FE is a miniature wirewound resistor specifically engineered for current sensing applications across various industrial sectors. Constructed with a CeramTec Rubalit 96% alumina ceramic core and precision-formed stainless steel end caps, this resistor offers exceptional stability and durability. The CN49W alloy resistance wire provides a temperature coefficient of ±20ppm/°C, ensuring accurate performance over a wide temperature range. Manufactured using computer numerical control (CNC) techniques, the WLAR030FE guarantees consistent product quality and is encapsulated with SUMICON 1100/1200 epoxy molding compound for enhanced protection. Its miniaturized dimensions and superior power-to-dimension ratios make it ideal for space-constrained designs.
