Power resistors handle high-energy pulse applications
Bourns, Inc. releases its Riedon BRF Series of precision power foil resistors for high-energy pulse applications. These power resistors offer power ratings up to 2,500 W and a temperature coefficient of resistance (TCR) as low as ±15 ppm/°C, making them suited as energy dissipation solutions for circuits that require high precision. Applications include current sensing, power management, industrial power control, and energy storage.
The power resistor series is available in two- and four-terminal options with termination current ratings up to 150 A. This enables developers to tailor the resistors to their exact design requirements, Bourns said.
Other key specifications include a resistance range from 0.001 to 500 Ω, low inductance of <50 nH, and load stability to 0.1%. The operating temperature range is -40°C to 130°C.
The BRF Series of power resistors is built using metal foil technology housed in an aluminum heat sink and a low-profile package. These precision power resistors are designed to meet the rugged and space-constrained requirements of high-energy pulse applications such as power converters, battery energy storage systems, industrial power supplies, inverters, and motor drives.
Available now, the Riedon BRF series is RoHS compliant. Click here for Bourns’ portfolio of metal foil resistors.
