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

Pulse Electronics Corp. recently introduced 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, these inductors are ideal 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. 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.

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.
