Ducon Condenser Pty. Ltd. manufactured Electrolytic, paper and mica capacitors, metalized and wirewound resistors from 1932 to 1963 for the electronics industry in Australia. In the early 1960’s they manufactured semiconductors.

Registered in Victoria in May 1932 [The Argus (Melbourne, Vic. 22. Feb. 1946 p. 19].

Becomes a subsidiary of the Plessy Co. Ltd. of UK (1963).

History:

The company was registered in Melbourne in July 1932 with first directors P. Dubilier, H.H. Hecht, J. Catzman and A.R .Persson. [1]

The company manufactured Ducon Aerovox brand Electrolytic Capacitors under license to the US Aerovox Corporation in 1938.[7]

In June 1949 the company acquired mica capacitor manufacturer Simplex Products Pty. Ltd.[2]

They entered an agreement with the US Company P.R. Mallory and Co. Pty. in 1954 to manufacturer and sell Mallory products in A/Asia. [3]

They expanded their Villawood factory to 269,460 ft² from 186,000 ft² in 1959.[4]

During 1960, they began manufacturing a range of semiconductor devices including germanium transistors and diodes and silicon rectifiers. The transistors and diodes were made under licence from Compagnie Generale de TSF (C.S.F.) France and the rectifiers from P.R.Mallory, USA. [5]

The Plessey Co. Ltd. of the United Kingdom acquired the company in August 1963. [6]
