Mon, 03/01/2010 - 7:38am
TT electronics' BI Technologies, a manufacturer of magnetic components including inductors, transformers and common mode chokes, has developed a high current surface mount power inductor. Designated the HA73 Series, the inductor features a high saturation core material and an operating frequency up to 800 kHz, while measuring 19.2 mm x 19.6 mm with a height of 12.2 mm. The HA73 Series inductors feature a typical rated inductance range from 13.5 µH to 29.5 µH, with a typical rated current range from 6.5A to 9A, depending on the device. The heating current ranges from 8A to 12A, with a saturation current from 9A to 13A. Typical DC resistance for the inductor ranges from 12.8mA to 28.6mA. Operating temperature ranges from -40°C to +155°C, and maximum temperature rise is +50°C.
