NTC thermistors placed in series with the supply, high in resistance when cold and low once warm, so the switch-on surge into a capacitive load is limited and little is dissipated in normal running. For power supplies, chargers and drives.
Thermistors whose resistance falls as temperature rises, in a steep and repeatable curve. Available in several formats and resistance characteristics for temperature measurement, compensation and over-temperature protection.
Working alongside your design team from the earliest stage, we help you select the right part for the application and, where a standard part will not do, develop customised components with our manufacturing partners such as lead length, termination and package size.
Thermistors are held in two families: NTC types for temperature sensing and compensation, then inrush current limiting types that control the switch-on surge. Both work from the same principle, that resistance falls as the device heats.
