Overview

The OAR5R010FLF is a 10 mOhm, 5W through-hole current sense resistor from TT Electronics designed for high-power monitoring. This metal element resistor features an open-air design that facilitates cooling and is built to withstand significant pulses while maintaining a 1 percent tolerance. Its flame-proof construction makes it suitable for critical safety circuits and power management systems.

Why Choose This Part

The open-air radial design allows for excellent heat dissipation and prevents PCB charring under high-load conditions. With a 5W power rating and pulse-withstanding capabilities, it offers high reliability in environments prone to transient spikes. Its safety-oriented flame-proof construction ensures the component fails gracefully without causing fire hazards.

Applications

Switch Mode Power Supplies (SMPS)
Used as a low-side current shunt for feedback loops in high-wattage power converters.
Motor Control Circuitry
Monitoring phase currents in industrial motor drives to detect overcurrent or stall conditions.
Battery Charging Systems
Precise measurement of high-current charging and discharging cycles in large battery packs.
DC-to-DC Converters
Implementing current-mode control and protecting sensitive components from power surges.
