Shielded, SMT power inductors suit small electronics
Designed for compact PoL and mobile devices, a family of six ultra-low profile SMT shielded inductors have been introduced by Pulse Electronics. The PA4330, PA4331, PA4332, PA4333, PA4334 and PA4335 inductors feature mounted height profiles from 1.0 to 3.2mm, making them suited for today's mobile computing, home automation, portable POS and other small handheld devices.
These 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 metalised core termination that provides excellent shock resistance characteristics without impacting the height of the part.
Glenn Roemer, Field Applications Engineer, Pulse Electronics, commented: "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."
The inductors are available in EIA standardised tape-and-reel packaging. Standard production lead time is eight weeks and samples are available immediately. Pricing for the ultra-low profile series in 10,000 unit quantities range from $0.11 to $0.13, with the standard low profile inductor, PA4333.XXXNLT, starting at $0.34
