SiC Schottky barrier diodes feature low forward voltage, high surge resistance
ROHM has recently announced the availability of 3rd generation SiC Schottky Barrier Diodes (SBDs) optimized for power supply PFC circuits in servers and high-performance PCs. The SCS3 series adopts a new structure that improves upon the industry-low VF characteristics of ROHM’s 2nd Generation SiC SBDs (1.35V @ 25C) while providing increased surge resistance. This contributes […]
40-W ac-dc open-frame power supply billed as world’s smallest
XP Power today announced the ECF40 series of single output 40 Watt ultra-compact AC-DC power supplies. These open frame convection-cooled units are capable of delivering the full output power of 40 Watts without the need for any external forced air flow up to + 50 degrees C. Believed to be the smallest 40 Watt open […]
