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.
Introduction of Highly Efficient Power Semiconductor for DDR type SDRAM, FPGAs by Renesas Electronics
Renesas Electronics has announced the release of a power semiconductor device which is designed for use as a dedicated power supply for DDR type SDRAM memory and large scale logic devices such as FPGAs used in PCs, servers and printers. The newly developed R2J20751NP is industry’s first POL converter with a 25 A maximum rating, which integrate MOSFETs and power supply controller in one single package helping system designers to realize power supply systems that are compact and energy efficient.
