Capacitors have been developed and manufactured here in eastern Thuringia since the late 1930s. ELECTRONICON is a globally recognised specialist in high-quality capacitors for reactive current compensation, harmonic filters, energy transmission, drive technology and DC links, as well as many other AC and DC applications. With its capacitor production, ELECTRONICON is the largest company within the SYSTEM ELECTRIC Group based in Gelnhausen. To this day, production is almost entirely concentrated in Gera.
