Pulse Electronics Power Business Unit has released a new high density line of shielded power inductors. The PA4318.XXXNL – PA4322.XXXNL series offer fully shielded construction for EMI and sizes ranging from 5.1 x 5.1 x 3.1 to 12 x 12 x 10mm.

These new platforms expand on existing Pulse products and offer increased energy storage density while maintaining industry standard footprints, allowing customers to easily complete their designs using Pulse Electronics components.

“These five new inductor platforms expands Pulse’s offering of high density shielded power inductors giving our customers more footprint options for their space critical designs”
John Gallagher | Staff Field Applications Engineer
