Bourns Launches 300W Thick Film Power Resistors
Bourns Introduces High-Power Riedon™ PF2270 Series Resistors for Demanding Power Applications
Bourns, Inc., a leading global manufacturer and supplier of electronic components for power, protection, and sensing solutions, has announced a significant expansion of its robust power resistor offerings with the introduction of the Riedon™ PF2270 Series of power resistors. Leveraging advanced thick film technology, these new resistors are presented in a widely recognized standard TO-227 package, ensuring easy integration into existing designs. The PF2270 series delivers impressive performance with low inductance, a high power rating of 300 W, and a broad resistance value range from 0.1 ohms to 100 kilo-ohms. Designers also benefit from flexible resistance tolerance options of 1% and 5%, allowing for precision in their applications.
This series is exceptionally well-suited for critical functions such as current limiting, precise current measurement, and efficient capacitor discharge applications. Its robust design and performance characteristics make it an ideal choice for direct integration into demanding systems like industrial motor drives, advanced power conversion solutions, and large-scale battery energy storage systems (BESS). The introduction of the PF2270 series significantly strengthens the Bourns® high-power resistor product portfolio, offering customers an even wider array of options to meet their diverse technical requirements and application needs.
