Coilcraft’s LPD5030V SMT transformer

The Coilcraft LPD5030V SMT transformer has two really important features — 1,500-Vdc winding-to-winding isolation and, at just 5 x 5 x 3 mm, a smaller size than any similar devices. The design was done by a team at Coilcraft headquarters in Cary, IL. Typical transformer designs come out much larger than inductor designs because they use different core and bobbin types to accommodate the multiple windings of transformers. The team was challenged to create one with the desired isolation that takes advantage of high-volume manufacturing techniques that are well established for simple inductors.

The development of the LPD5030V was a true example of designing for manufacturability and the team was able to reduce the size, cut wide part-to-part parameter variations, and speed up the manufacturing cycle.

There has been a great deal of interest in the LPD5030V since its launch with evaluation sample requests coming in from around the globe. Product demand has been particularly strong in the U.S. and across Europe.
