What Eichhoff Capacitors does

EICHHOFF Kondensatoren GmbH (trading as Eichhoff Capacitors) is a German family-owned manufacturer of passive electrotechnical components, founded in 1931 and headquartered in Schlitz, Hesse. The company designs and produces electromagnetic compatibility (EMC) components — including self-extinguishing paper capacitors in X1, Y2 and X1Y2 safety classes, radio-interference chokes, suppression filters, and RC combinations — as well as inductive components for power electronics (PFCs, storage chokes, sine filters, power transformers) and Powerline Communication (PLC) systems comprising modems, line filters, blocking filters, capacitive and inductive signal couplers, and coupling capacitors.

Eichhoff serves industrial OEMs across at least nine verticals — electrical household appliances, power tools, lighting, ICT, medical technology, drive technology and automation, railway, e-mobility, and smart grid/energy utilities — with primary emphasis on white goods manufacturers and energy/grid operators. The business model combines custom engineering development and series production with unit-based pricing under EXW Schlitz delivery terms, 30-day net payment terms, and 10% advance payments on orders exceeding EUR 50,000. Production is centralized at the wholly-owned subsidiary EICHHOFF Components Bulgaria EOOD (Vidin, established 2002, 4,300 sqm facility opened 2008), which operates VDE- and UL-monitored processes and additionally offers third-party Electronics Manufacturing Services (EMS) and injection molding.

Supporting capabilities include an in-house EMC testing laboratory, in-house tool and special machine construction, custom plastic part design, and TÜV DIN EN ISO certification. The current managing director is Ing. Bernd Luft, who became part of the ownership group following a 2010 change of ownership that realigned management and product strategy, strengthening the German development base while optimizing the European production location. The company markets itself as a German "Hidden Champion" approaching its centennial.
