Providing greater circuit stability and measurement accuracy, the four new series support market application demands for enhanced power dissipation and increased reliability
RIVERSIDE, Calif., November 26, 2025 - Bourns, Inc., a leading manufacturer and supplier of electronic components for power, protection, and sensing solutions, today announced that it has increased its Riedon™ High Power Thick Film Resistors by Bourns with four new product series. The PSD220S, PSD227, PSD126 and PSD220T-50 Series Resistors are available in TO-126, TO-220, TO-227, and SMD DPAK packages. They feature power ratings from 25 to 200 W, low inductance and excellent pulse handling capabilities that enable enhanced circuit stability and measurement accuracy.
The four new resistor series are designed to match market demands for greater power dissipation and higher reliability. Meeting these demands, they deliver a wide resistance value range from 20 milliohms to 100 kilohms and have Temperature Coefficients of Resistance (TCRs) ranging from ±50 to ±600 ppm/°C. These features along with their rugged construction and reliable thermal performance make the four PSD Series resistors ideally suited for demanding designs such as power supplies, motor drives, test and measurement equipment, rectifiers, capacitor discharging applications and snubber circuits. Additionally, each series can be custom-tailored to meet application-specific requirements.
The Riedon™ PSD220S, PSD227, PSD126 and PSD220T-50 Series High Power Thick Film Resistors by Bourns are available now through Bourns’ authorized distribution partners and are RoHS* compliant. For more detailed product information, please see: bourns.com/products/resistors/high-power-resistors.
