Planar Transformers Tout High Performance From Space-Saving Designs
Thu, 10/06/2011 - 12:17pm
Standex Electronics introduced a full lineup of planar transformers which are asserted to deliver high-performance from compact, low-profile designs. The planar transformers provide low leakage inductance and repeatable capacitance. Available in standard or custom designs, the transformers are appropriate for various demanding applications including military/aerospace, medical, hybrid and electric vehicles, LED lighting, and renewable energy such as wind and solar. Manufactured of windings that are made of copper foil lead frames sandwiched between ferrite cores, Standex offers four families of planar products to suit specific application parameters from 180 W to 10 KW. Each family features a large core surface that promotes heat transfer. In addition AC resistance and proximity Cu loss are minimized. Low turns count also improves Cu loss. Optimized core cross section lowers core loss while PCB construction minimizes Cu loss.
