LAS VEGAS, NV (May 12, 2009) — Providing design engineers with a robust, cost-effective through-hole device that requires minimal board space, TT electronics BI Technologies has extended its family of high-current, low-loss power inductors.  The new HM58 Series inductor features a heavy-gauge coil wire and exhibits a saturation current rating up to 60A at frequencies to 1MHz, making it ideal for motherboard and computer power applications.

 “We’ve seen an increased demand for an inductor that delivers high-performance operating specifications but requires minimal PC board space,” said Donna Schaefer, application engineering manager for BI Technologies.  “With its through-hole configuration and three open sides, the inductor requires a footprint of only 11mm x 11.5mm. As such, we are seeing the inductor used in a number of voltage regulator applications where board space is constrained.

 The RoHS-compliant HM58 Series high current cube inductor features inductance values from 0.36mH to 1.30mH, depending on device. DCR ratings are from 0.65mohm to 1.05mohm, with tolerances to +/-5%.  Operating temperature range is from -40°C to +125°C. The inductor is available in standard tray packaging. BI Technologies will also produce devices outside these specifications to meet customer requirements.
