Type: Multiplexing Equipments
Place Made: Japan
Date Made: 1941
SIZE: L10.5* W7* H13cm
Function/Purpose: Used in early high-power radio stations, such as the ultra short wave coast radio stations, variable capacitors are a major component when applying oscillation, tuning, and amplification (written by WU, LONG-SHAN).
Characteristics: This is a fixed capacitor, which uses mica as the insulator between two polarities. It can stand 4K voltage with the capacitance of 0.05 μF (written by WU, LONG-SHAN).
