thermistors for limiting of Inrush current

thermistors for limiting of Inrush current Description

WMF21 series thermistors are used for limiting the Inrush Current in the power supply loop of every kinds of power supply, ballast / CFL etc. and the heating loop of CRT of color TV / monitor, heater, filament etc.
The WMF21 series thermistors is the radial leads resin coating type products, it has the characteristic of small bulk, high power, strong limiting of inrush current, quick response, , high reliability, etc.
The temperature is decreased while the Material Consistent(B) of thermisters is increasing and the Remain Resistance is decreasing. The higher is the Thermal Capacity, the stronger is the capability of limiting the Inrush Current. It is direct proportion to the product of the Thermal Time Constant (T) and Thermal Dissipation Constant (d) .
The WMF21 series thermistors has so wide application area, which is mainly used in Switching Power Supply, UPS Power Supply, CFL, Ballast, Circuitry of Power Supply, etc.
