Electronic contract manufacturers supply manufacturing services, contract design, and aftermarket services. Although they design and manufacture most of their products, most electronic contract manufacturing companies do not build their own magnetic components like transformers, inductors, and coils.
Butler Winding is a reliable high quality electronic transformer and inductor provider for electronic component manufacturers. Since 1984 Butler Winding has been designing transformers and inductors that meet your OEMs needs. Butler Winding provides reliable shipping to fulfill their manufacturing projects. Butler Winding specializes in precision work on custom electronic transformers and inductors for electronic manufacturer use. We design prototype, test, and build transformers and inductors to meet your manufacturing needs.
Butler Windings uses magnetic cores made of various materials including ferrite, powdered iron, MPP, Sendust, KoolMu, Silicon Iron, and Permalloy. We use core shapes including toroid, U, E, EP, RM, Pot, EC, EFD, ETD, and PQ shaped cores. We use magnet wire from 12 AWG to 40AWG, litz wire, foil wire, and stranded or bifilar wire. Coil construction methods include bobbin, toroid, machine wound, hand wound, open frame, encapsulated, surface mount, thru-hole, single layer and multi-layer.
All components are 100% tested. Tests can include inductance, biased inductance, leakage inductance, turns ratio, polarity, magnetizing current, and both AC and DC HIPOT. Applications include step up and step down transformers, power inductors, common mode inductors, pulse transformers, magnetic amplifiers, saturable reactors, flyback transformers, isolation transformers, shielded transformers, gate drive transformers, current transformers, and air core coils. Operating frequencies go from line frequency to several hundred MHz.
