UAL Riedon™ Power Resistors

Bourns UAL Riedon™ Power Resistors are aluminum-housed wire wound resistors designed to MIL-R-39009/MIL-R-18546 power ratings. These resistors feature a 0.01KΩ to 250KΩ resistances, 5W to 50W power ratings, excellent pulse handling, and ±20PPM/°C low TCR. The UAL power resistors are available in various terminal options. These resistors operate within -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.
