Overview

The OAR5R015JLF is a 15 mOhm, 5W open-air current sense resistor designed for through-hole PCB mounting. Its unique open-loop construction allows for high power dissipation and low thermal resistance by maximizing airflow around the resistive element. This component is specifically engineered for precision current monitoring in high-current power stages.

Why Choose This Part

The open-air design offers excellent heat dissipation without the thermal mass of traditional molded resistors, allowing for a 5W power rating in a compact footprint. It features an operating temperature range of -40C to 125C and provides negligible inductance, making it suitable for high-speed switching applications.

Applications

Switch Mode Power Supplies (SMPS)
Utilized in the primary or secondary side for high-side or low-side current sensing to manage power regulation.
DC-DC Converters
Provides precise feedback for overcurrent protection and current-mode control loops in power conversion modules.
Motor Control Feedback
Acts as a shunt resistor to monitor phase currents in industrial motor drives and high-power BLDC controllers.
Battery Management Systems (BMS)
Monitors charge and discharge currents in high-capacity battery packs to ensure safe operating limits.
