BI671 HA73 Series PR_imageTT electronics BI Technologies, a leading 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 800kHz, while measuring just 19.2mm x 19.6mm with a height of 12.2mm.

“The core material utilized in these inductors enables them to offer high power density with superior efficiency and minimal power losses in an extremely small package,” said Donna Schaefer, application engineering manager for TT electronics’ BI Technologies. “The complete package design and core materials makes these inductors ideal for use in DC-to-DC converter power applications.”

The HA73 Series inductors feature a typical rated inductance range from 13.5µH to 29.5µH, with a typical rated current range from 6.5A to 9A, depending on the device. Heating current ranges from 8A to 12A, with a saturation current from 9A to 13A. Typical DC resistance for the inductor ranges from 12.8m? to 28.6m?. Operating temperature ranges from -40°C to +155°C, and maximum temperature rise is +50°C. BI Technologies will also produce devices outside these specifications to meet customer requirements.
Typical pricing for the HA73 Series power inductors ranges from $1.40 to $1.58 each in quantities of 10,000 pieces. Lead time is from 10 to 12 weeks.
