Ohmite TFSO Thick-Film Power Resistors

Ohmite TFSO Thick-Film Power Resistors are non-inductive thick-film resistors offering 100W high power density in a SOT-227 package. Available in a wide range of resistance values, the TFSO offers two possible configurations with two or four easy-to-connect terminals. These Ohmite power resistors are made from quality materials for optimum reliability and stability with very low partial discharge. TFSO resistors serve a variety of applications, including high-voltage, high-frequency, snubber resistors, and power supplies.
