Germanium bipolar transistors

Summary[edit]

Description
English: EFT125 vs EFT123 vs EFT322, PNP germanium bipolar transistors.

The photo shows the differences between the types of packages used for the transistors at the beginning of production in the factory, back in 1962, comparing the transistor on the left, an EFT125, with the transistors produced later, after 1963, the transistor in the middle, an EFT123 and the later series, produced in the version of classic TO-1 encapsulation, the transistor on the right EFT322.

Manufactured in Romania, I.P.R.S. Baneasa, 1960s.
