STACKPOLE Adds Three Shielded Product Series to its Power Inductor Offering

Stackpole Electronics, Inc. has further expanded its power inductor product line with the addition of three new magnetically shielded series. The new PSDB, SFM and PDRH Series are intended to provide design engineers with solutions for designs limited by height, footprint and performance.

Power inductors are inherently bulky and normally generate magnetic fields that can damage sensitive components nearby. As the trend towards miniaturization in electronics continues, circuit designers will demand better performance from smaller parts. Stackpole's new magnetically shielded power inductors products are designed to provide greater versatility by delivering excellent electrical performance in a variety of package sizes and configurations without sacrifices in cost or performance.

"Power inductors are notoriously problematic in circuit design because of their size and inflexibility," says Mark Hunnell, a member of Stackpole's engineering team. "With Stackpole's new PSDB, SFM and PDRH inductors, design engineers are given the tools to continue the miniaturization trend without the typical tradeoffs."

The PSDB Series features an electrode connected directly to the ferrite core. With inductance values from 1.3 to 1000µH and current capabilities up to 10A, the high-power and high-saturation design of the PSDB makes it a suitable choice for dc-dc conversion. To provide design flexibility where profile limitations apply, the PSDB is available in three heights from 3 to 5mm. Furthermore, the square shape design and tape and reel packaging make automatic insertion easy to implement.

Typical pricing is $0.34 each. Lead times are eight to 10 weeks, with samples available in three to four weeks.
