The Riedon™ BRF Series by Bourns features exceptional power ratings and TCRs delivering excellent energy dissipation for precision circuits
RIVERSIDE, Calif., November 24, 2025 - Bourns, Inc., a leading manufacturer and supplier of electronic components for power, protection, and sensing solutions, today launched its Riedon™ BRF Series Precision Power Foil Resistors by Bourns. Designed for high-energy pulse applications, BRF Series resistors feature exceptional power ratings up to 2500 W and a temperature coefficient of resistance (TCR) as low as ±15 ppm/°C. These features make them excellent energy dissipation solutions for circuits requiring high precision. In addition, this series is available in 2- and 4-terminal options with termination current ratings up to 150 A, giving developers the flexibility to tailor these resistors to their exact design requirements.
The BRF Series is built using metal foil technology housed in an aluminum heatsink and a low-profile package. Bourns specifically constructed its latest precision power resistors to meet the rugged and space-constrained requirements of a growing list of high-energy pulse applications such as power converters, Battery Energy Storage Systems (BESS), industrial power supplies, inverters, and motor drives. By combining outstanding power capacity with precision temperature stability, the BRF Series provides a versatile solution that supports the growing need for efficient, reliable, and accurate energy dissipation in next-generation high-performance systems.
The Riedon™ Model BRF Series High Precision Power Resistors by Bourns are available now and are RoHS* compliant. For additional information, please see: bourns.com/products/resistors/metal-foil-resistors.
*RoHS Directive 2015/863, Mar 31, 2015 and Annex.
