TDK-EPC has exhibited three sample kits of ceramic PTC (positive temperature coefficient) thermistors from EPCOS. The components of the "SMD PTC Thermistors for Limit Temperature Sensing and Superior Series" sample kit are designed for use as temperature sensors in LED lamps, power supplies and notebooks. The kit contains samples for sizes 0402, 0603, and 0805 across the temperature range between 75 and 145°C. All thermistors are certified to AEC-Q200 and are suitable for reflow and wave soldering.
The "SMD PTC thermistors for over-current protection" sample kit contains components for surge current protection applications. They are used as self-resetting fuses and as such limit currents to uncritical values in the event of overload or short circuit. These thermistors are available in 0603, 1210, 3225 and 4032 sizes. The "PTC thermistors for inrush current limiters" sample kit is suitable as inrush current limiters in AC/DC inverters, frequency converters, air-conditioning systems, pumps and other kinds of equipment that exposes the power line to high inrush currents.
