Magnetics, from signal-level toroids to 750+ KVA
01 / 05 · Transformers Step-down, isolation, three-phase, and everything between
Single- and three-phase power, control, and isolation transformers — wound to your voltages, footprint, and agency requirements.
02 / 05 · Toroidals Compact, quiet, efficient
Low stray field and low hum for medical, audio, and instrumentation — at a fraction of the size of laminated cores.
03 / 05 · Inductors Inductors built around your circuit
Power and filter inductors modeled before anything is wound, so the first prototype is close to the last.
04 / 05 · Chokes Clean power, passed the first time
Common- and differential-mode chokes designed with agency testing in mind.
05 / 05 · Power solutions From component to complete assembly
Enclosed units, multi-component assemblies, and power subsystems — engineered, built, and tested as one part number.
Industries
Built for programs that can't fail.
Mars rovers. Nuclear submarines. Diagnostic imaging. Tesla Superchargers. The applications vary — the standard doesn't.
