MSR Riedon™ Current Sense Resistors

Bourns MSR Riedon™ Current Sense Resistors are bare metal element devices designed to offer excellent and rugged performance. These resistors feature 0.005Ω to 0.10Ω resistances, 1W, 3W, or 5W power ratings, ±1% resistance tolerances, superior pulse capabilities, and ±20PPM/°C Temperature Coefficient of Resistance (TCR). The MSR resistors operate within the -55°C to 275°C temperature range and are RoHS compliant. These resistors are used in motor drives, smart meters, solar inverters, capacitor recharge/discharge circuits, industrial power supplies, and current sensing applications.
