TFSO Series

TFSO Series

100 Watt SOT227 Package

Thick Film Power

The TFSO is a non-inductive, thick film resistor offering high power density in a SOT-227 package. Available in a wide range of resistance values, the TFSO has two possible configurations with two or four easy to connect terminals. The resistors are made from quality materials for optimum reliability and stability with very low partial discharge. Resistors with alternative terminations are available and custom/made-to-order designs are available.
