478:. Capacitor manufacturing was thus no longer a core business for Ericsson – and likely why it was sold. Evox Rifa closed down their Kalmar factory in 2005, which then had about 220 employees. Some operations in Kalmar (development of film capacitors, sales and customer service) were then moved to a subsidiary, Dectron AB, in

initially had no desire to invest in RIFA, due to their ownership of rival capacitor manufacturer, AB Alpha, which they bought in 1929 and integrated into
Ericsson's own capacitor manufacturing. After the war, however, demand for Ericsson's products increased and a shortage of capacitors arose. On 29

On 1 March 1988, RIFA sold their capacitor business to
Finvest Oy, who also assumed the RIFA brand. Capacitor production for RIFA by 1988 constituted a fifth of Ericsson's profit and employed roughly 1,400 people. Finvest Oy previously owned the capacitor manufacturer Evox. After acquiring RIFA,

December 1946, Ericsson purchased a 50 percent share of RIFA from other investors, leaving ASEA as the only other principal owner. On 1 January 1947, Ericsson bought out ASEA's share and became the new, sole owner of RIFA. Ericsson subsequently folded AB Alpha into RIFA.

Evox Rifa AB was thereafter split across three factories: a factory in Gränna for the manufacture of electrolytic capacitors; a factory in Kalmar for the manufacture of paper and precision capacitors; and a factory in Kista for the development of integrated circuits.

Swedish innovation and Swedish patents. One of the stamps was dedicated to RIFA and the stamp depicts a Subscriber Line Integrated Circuit (SLIC) for managing subscriber steps in Ericsson's telephone exchanges. The stamp had a denomination of SEK 2 70

Finvest Oy merged the two companies into Evox Rifa AB. RIFA's circuit and silicon business (integrated circuits) was renamed to
