Tondi Elektroonika
Tondi Elektroonika, formerly known as Tallinna Pooljuhttakistite Tehas, Hans Pöögelmanni nimeline Tallinna Raadiotehnika Tehas and Hans Pöögelmanni nimeline Elektrotehnika Tehas, as well as Factory A-1381, was a factory for electrotechnical components located in Tallinn, Estonia. It was a significant component of the Soviet military-industrial complex.
When the centralization of the USSR economy resumed in 1966, the national councils were abolished and the factory was subordinated to Moscow and renamed Factory A-1381. As the public name of the numeric factory was not allowed to contain location, the factory was named after September 1, 1966, as the Hans Pöögelmann electrical engineering factory. Under this name, the company operated in all its glory to the formation of Tondi electronics in 1991. During this time, the P-N-P-type bipolar transistors and thyristors, the P-channel output transistors and the transistor pair and the outdoor transistor input were produced. In addition, there were some consumer products in production and hearing -proofs about medical electronics.
Production
Components
The factory has manufactured photoresistors, varistors, transistors, thyristors and microchips.From 1959 to 1978, the factory manufactured temperature-sensitive photoresistors 04-AN for use in Soviet military rocket guidance systems. This brought the factory under the official military-industrial complex umbrella, and the factory was assigned a number — A-1381 — and the location reference was removed from the factory's name.
