PF2270 Riedon™ Power Resistors

Bourns PF2270 Riedon™ Power Resistors are engineered to meet the growing need for higher performance within size constraints, achieving high power capabilities and enhanced reliability. These chassis-mount resistors feature thick-film technology in a standard TO-227 package with a wide resistance value range from 0.1Ω to 100KΩ and resistance tolerances to ±1%. Compared to traditional wirewound power resistors, the PF2270 series offers significantly lower inductance (14nH) and a condensed form factor in the same power rating. The PF2270 resistors also provide superior pulse-handling capabilities compared to thin-film resistors. The compact design features high power dissipation, power ratings up to 300W, and moisture-resistant encapsulation. Bourns PF2270 Riedon Power Resistors are ideal for current limiting and measurement, capacitor recharge/discharge circuits, industrial motor drives, and power conversion applications.
