About GT elektronik

GT elektronik is an owner-managed family business based in Nabburg (Upper Palatinate) and has been developing and producing custom wound components for over 30 years. The product range includes transformers (EI/EE, UI and toroidal core types, 0.35 to 1000 VA), coils (motor, charging, ignition, relay, sensor, magnet and antenna coils, also as self-supporting bake-varnish coils), toroidal cores made of grain-oriented SiFe transformer sheet, chokes (storage, filter, PFC, interference suppression, current-compensated and damping chokes), transmitters as well as current transformers for PCB, cable and DIN rail mounting. Production takes place in small, medium and large series with potting technology (open, vacuum-impregnated or vacuum-potted) and construction according to EN 61558-1 with its own UL insulation system Class F. More than 1000 employees serve more than 250 industrial customers from measurement, control and regulation technology, renewable energies and medical technology. Production takes place in own workshops in Germany and India as well as with a manufacturing partner in Romania.
