Vishay 307C Lighting Thermistors Datasheet
This datasheet describes the Vishay 307C series of lighting thermistors designed for use in compact fluorescent lamps (CFL) and electronic ballasts. These PTC (Positive Temperature Coefficient) resistors function as electrode preheat devices to extend lamp life and ensure quiet, flicker-free operation. The components are developed in cooperation with leading ballast designers and are available in both standard and custom configurations.
