This is a vintage single-dial decade box capacitor, used primarily in electronics labs, repair shops, and audio testing to select specific capacitance values by turning the dial.
Manufacturer is Cornell-Dubilier Electronics Division (under parent corporation Federal Pacific Electric Company). Maximum Voltage Ratings: 600 Volts D.C. / 220 Volts A.C., and measurement units are in Microfarads (μF).
The unit allows you to place a precise amount of capacitance into an electronic circuit. By turning the dial from 0 to 10, each step adds 1.0 microfarad, creating a range of 0 to 10.0 μF.
Model #: CDC-5, Serial #: 83282
