Ultra-Low Profile, Shielded, SMT Power Inductors for Small Electronic Devices

Sept2_PulsePulse Electronics Corp. has announced 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 1.0 mm to 3.2 mm, these inductors are suited for today’s mobile computing, home automation, portable POS and other small handheld devices.

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. The ultra-low-profile design has a metalized core termination that provides improved 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.

“These are the smallest power inductors that Pulse has produced,” said Glenn Roemer, field applications engineer, Pulse Electronics. “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.”

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.
