Ceramic Capacitors

K10U-2 is a packageless ceramic capacitor. The copies shown in the photo were used in a BW TV. The capacitor was inserted into a slot in printed circuit board soldered to the printed conductors on the opposite side.

This capacitor is non-inductive. Covers are made of silver. Due to the low heat resistance of ceramics, capacitors must be heated before soldering to prevent damage.







Earlier tubular capacitors, capacitance designation - 180mmF, fastening of the leads - two turns around the tube:



A couple more:










Ceramic feedthrough capacitors K10-51



Ceramic tubular capacitors, presumably K10-38. They are interesting because they look like MLT-0.5 resistors. They were used in the channel selector SK-M-24-2S.



Presumably glass capacitor K21-7. It was used in the radio channel module. Outwardly, it is a bit similar to the KM-5 in color and shape, but it is thicker and has a different terminal design.



The famous capacitors KM-5, "green". One of the good capacitors of domestic production. They have a good TKE, they were often used as noise suppressors in digital electronics - 1 piece per microcircuit. During the infamous buying up of precious metals, they were massively destroyed due to their content of silver, platinum and palladium.

The left "brick" in the photo is K10-48.



Capacitors that are somewhat similar to K10-48 are KLS. Outwardly, they differ in that one of their sides is uneven. In the photo below, this, unfortunately, is not visible, since the uneven side is from below.
