PF2270 Series Thick Film Resistors Provide Excellent Heat Dissipation and Thermal Efficiency in Motor Drives, Power Conversion, and Energy Storage Systems

Riverside, Calif. — July 1, 2025 — Bourns, a leading manufacturer of electronic components for power, protection, and sensing solutions, introduces a new thick film resistor series that offers high thermal resistance in a compact TO-227 package. The Bourns® Riedon™ PF2270 series power thick film resistors feature thick film technology and excellent pulse withstand capability, dissipating up to 300W of power when used with a heatsink. Their low inductance design and high power dissipation capability make them an ideal solution for high-performance electronic designs, including industrial motor drives, power conversion, and energy storage systems.

The advanced design of the TO-227 package allows for operating temperatures up to +175°C. The PF2270 series offers a wide resistance range from 100mΩ to 100kΩ with 1% and 5% resistance tolerance options. These features provide excellent current limiting performance, precise current measurement, and excellent capacitor discharge capability, making it ideal for applications requiring high power density and improved reliability.

Bourns® Riedon™ PF2270 series power thick film resistors are available now and are RoHS compliant.
