Product Description

The PZFR0805D4R50L9 is a precision 4.50mΩ ultra-low ohmic resistor from the PZFR series, designed for high-current sensing applications. As an 0805 chip resistor, it features compact dimensions (2.0mm x 1.25mm) and operates within -55°C to +155°C temperature range with ±1% tolerance. Supporting up to 0.5W power rating at 70°C, this surface-mount component directly integrates with current monitoring circuits in power supplies, motor controls, and battery management systems. Its key advantages include low temperature coefficient (±50ppm/°C), excellent stability under thermal stress, and solderability compliant with automotive-grade standards (AEC-Q200). Primarily used in automotive electronics, industrial automation, and renewable energy systems, the resistor requires careful thermal management in high-power-density designs. The nickel-chromium alloy construction ensures reliable performance in harsh environments.
