Providing design engineers with a compact power device in a cost-efficient package, TT electronics BI Technologies has developed a tight DCR surface-mount power inductor. Designated the HM69T series, the inductor measures 7.4mm x 7.2mm, with a height of 5mm.

"The compact footprint makes the HM69T series inductor ideally suited for space-saving designs, including those applications with limited printed circuit board space," said David Smolik, director of product development for BI Technologies. "Coupled with a tight DCR tolerance of 3 percent and cost-efficient packaging, the inductor is specified for high volume power supply applications, such as voltage regulators and power circuits for central processing units."

The HM69T surface mount power inductors feature inductance values of 90-, 100- and 150nH, with rated DC current of 57-, 52- and 27A, respectively. DCR tolerance is to 3 percent, with typical DCRs of 0.298m. Operating temperature ranges from -40C to 125C, with a maximum temperature rise of 40C.
