We’re pleased to announce the release of a family of six new, ultra-low profile, SMT shielded inductors for compact point of load and mobile devices.

With mounted height profiles of 1.0mm to 3.2mm, they’re a valuable addition to our existing lineup of power inductors and are ideal for today’s mobile computing, home automation, portable POS, and other small handheld devices.

Glenn Roemer, Field Applications Engineer for Pulse Electronics Power BU said:

“These are the smallest power inductors that Pulse has produced. Noise and EMI in electronic circuits are always a concern in compact computing environments due to the proximity of the parts.  Finding components with high energy storage density in small form factor packages has also been a challenge. Pulse now has a full complement of inductors to help our customers by providing a new solution for small electronics.”

Key Features

These new ultra-low profile inductors have core geometries and construction that enable high currents with no radiated magnetic fields to interfere with associated components. By eliminating flux leakage, the high energy storage density and EMI performance are industry-leading. The ultra-low-profile design has a metalized core termination that provides excellent shock resistance characteristics without impacting the height of the part.

The family consists of six series of parts, the PA4330, PA4331, PA4332, PA4333, PA4334, and PA4335, which vary by footprint, current rating, and inductance range.

You can browse and download the datasheets for each series on our Drum Core Inductors page.

Ordering & Samples

The inductors are available in EIA standardized tape-and-reel packaging.  Standard production lead time is eight weeks. Samples are available immediately. Pricing for the ultra-low profile series in quantities of 10,000 range from $0.11 to $0.13, with the standard low profile inductor, PA4333.XXXNLT, starting at $0.34.
