What HAHN does
HAHN GmbH & Co. KG is a privately held, family-owned German manufacturer of wound electrical components, founded in 1949 and headquartered in Hungen, Germany. The company designs and produces small transformers (EI and UI series print transformers, 0.35 VA to 200 VA), switch-mode power supply transformers (EF-series flyback transformers up to MHz-range frequencies), ignition transformers and electronic ignition devices for gas-condensing and burner systems, and EMC components (common-mode chokes, passive and active PFC chokes). Manufacturing runs across three wholly owned production sites — Hungen (HQ), Güsten in Germany (established 1998), and Novovolynsk in Ukraine (established 2005) — supported by an in-house special machine and tool construction capability that enables rapid prototyping and 2-week sample production.
HAHN's portfolio is roughly two-thirds custom-engineered solutions and one-third standardized series products, certified to ISO 9001:2015, VDA 6.3, ENEC, UL (including multiple UL-listed insulation systems of classes B and F), RoHS, REACH, CE/UKCA, and applicable DIN EN standards. End markets served include industrial charging technology (forklifts, autonomous transport), medical technology, heating technology, energy technology, and drive technology, with over 50% of revenue from exports through a distribution network spanning more than 50 countries via partners including Arrow Central Europe, Anglia Components, TME, Texim Europe, Melchioni, and K. MECS.
Revenue mechanics are B2B hardware sales of components, supplemented by ENEC/UL certification support and design-in consulting services. Pricing is quote-based, with standard products available from stock through distributors and custom solutions priced on specification. The company is led by managing directors Marta Hahn and Klaus Dieter Hahn and remains wholly family-owned with no external investors, generating revenue disclosed only via third-party channels and represented operationally by a 500+ employee workforce and more than half a billion cumulative components produced since 1969.
