USF300 Series Film Resistors

Caddock's film resistors well suited for demanding precision analog electronics applications

Image of Caddock Electronics' USF300 Series Film ResistorsCaddock Electronics' USF300 series of film resistors provides a wide resistance range of 50 Ω to 25 MΩ. These resistors are available in three models: USF340 (300 V, 0.33 W), USF370 (1400 V, 0.75 W), and USF371 (2500 V, 0.75 W).

The USF300 series resistors are manufactured with an aluminum oxide (alumina) ceramic sandwich that offers exceptional thermal performance. The thermal conductivity of the alumina package provides good heat flow away from the resistor element, minimizing the temperature rise in the resistor. This is contrary to plastic molded low TC foil resistors, which cannot provide these thermal benefits.
