4X 20D20 NTC Thermistor for Limiting Inrush Current of CFL Ballast Black

Descrição de 4X 20D20 NTC Thermistor for Limiting Inrush Current of CFL Ballast Black

1. The WMF21 series thermistors are used for inrush current limiting in power supply loops of various types of power supplies, ballasts/CFLs, etc., and in heating loops of CRTs for color TVs/monitors, heating devices, filaments, etc. 2. The temperature decreases as the material consistency (B) of thermistors increases and the residual resistance decreases. The higher the heat capacity, the stronger the inrush current limiting capability. It is directly proportional to the product of the thermal time constant (T) and the thermal dissipation constant (d). 3. The WMF21 series thermistors are radial lead resincoated products. They feature low mass, power, inrush current limiting, fast response, long lifespan, reliability, etc.
