PQ Series Planar Inductors

Standex-Meder Electronics PQ series planar inductors are steadily replacing the need for traditional wire-wound inductors in many industries. Electric vehicles, solar inverters, wind power, aviation, healthcare, and industrial manufacturing are just some of the areas where this technology is gaining ground. While the windings of wire-wound inductors are used with round wire, the planar's windings are built by utilizing flat copper layers (PCBs) or plated flat copper windings (lead frames) to create a laminate-style winding construction. The result is a compact, high-power density planar inductor that is typically 30% of the volume and weight of a traditional wire-wound inductor. This size reduction eliminates many of the design constraints associated with wire-wound inductors, and the planar inductor's other characteristics offer additional benefits. With a very-low profile, excellent thermal characteristics, high repeatability, and low leakage inductance, planar inductors can easily meet the needs of modern applications.
