One of Würth Elektronik’s most important SMT high-current inductor innovations is to expand its WE-HCM series portfolio with 1012, 4030, and 5030 packages.
The flat-wire coils with MnZn core are characterized by extremely low resistance, low core losses, and a very high current carrying capacity. With their small footprint, the devices are the first choice of developers and manufacturers for new, more compact device designs.
WE-HCM1012 high-current inductor
The WE-HCM1012 high-current inductor takes up just 10x6 mm of space on the board and accommodates its flat-wire coil in a 12 mm high package. The rated current of 84 A and saturation current over 125 A are also high. WE-HCM1012 is available in variants with inductances of 0.07 µH 0.1 µH, 0.12 µH, and 0.15 µH.
The two new WE-HCMs in 4030 and 5030 packages are also unusually space-saving in their footprint and height. As they are only 3 mm high, they are suitable for use in convertible notebooks and tablets, for example.
Applications
Applications include multiphase switching regulators, CPU/RAM power supply, power PC, or graphics cards. Their saturation current goes up to 45 A and the rated current is 59 A. All WE-HCM versions are specified for an operating temperature range from -40 to +125°C.
The new WE-HCM are available from stock without a minimum order quantity. Würth Elektronik provides developers with free samples on request.
