TDK-EPC has released three new sample kits for ceramic PTC thermistors “SMD PTC Thermistors for Limit Temperature Sensing/Superior Series” are designed as temperature sensors in such devices as LED lamps, power supplies and notebooks. The other sample kit, the “SMD PTC Thermistors for Overcurrent Protection” contains components for surge current protection applications, which are used as self-resetting fuses and as such limit current to uncritical level in event of overload or short circuit. And finally, the sample kit “PTC Thermistors for Inrush Current Limiters” contains component that are suitable for inrush current limiters in AC-DC inverters, frequency converters, air conditioning systems, pumps as well as other type of equipments that exposes the power line to high inrush currents.
TDK-EPC has successfully developed SMD Series PTC (Positive Temperature Coefficient) thermistors for limit temperature measurement. The new thermistors come in case sizes of 0805, 0603 and 0402. They are designed for over temperature protection in industrial equipment as well as consumer and automotive electronics and IT applications. They have response temperatures from 70 to 145 degrees Celsius in steps of 10K depending on the series. Read more
