Bourns' Riedon™ BRF Series Offers Superior Power Rating and Low TCR for Superior Energy Dissipation in Precision Circuits

Riverside, Calif.—November 24, 2025—Bourns, a leading manufacturer of electronic components for power, protection, and sensing solutions, introduces the Riedon™ BRF Series of precision power foil resistors. Designed for high-energy pulse applications, the series features an impressive power rating of up to 2500 W and a low temperature coefficient of resistance (TCR) of ±15 ppm/°C. These characteristics provide an excellent energy dissipation solution for circuits demanding high accuracy. Additionally, the series offers two- and four-terminal options with termination current ratings up to 150 A, providing developers with flexible configurations to meet their design requirements.

The BRF Series utilizes metal foil technology and a low-profile package encased in an aluminum heatsink. Bourns specifically designed this latest precision power resistor to meet the robustness and space-saving requirements of the growing number of high-energy pulse applications, including power converters, battery energy storage systems (BESS), industrial power supplies, inverters, and motor drives. Combining excellent power capability with precise temperature stability, the BRF Series offers a versatile solution for the efficient, reliable, and accurate energy dissipation needs of next-generation, high-performance systems.

Bourns' Riedon™ BRF series precision power resistors are now available and are RoHS compliant(※1) and halogen-free(※2).
