Description
Д2 diodes: Д2Б, Д2В, Д2Г, Д2Д, Д2Е, Д2Ж, Д2И are germanium point-contact diodes. Their main purpose is the detection and conversion of signals with a frequency of up to 155 MHz. Д2 diodes are available in a glass case with flexible leads. Anode is marked with a colored dot or strip in the form of a ring.
