MC-140-S

10PF - 140PF 1.5KV VARIABLE CAPACITOR - vintage single-section, air-variable tuning capacitor widely used in radio frequency (RF) applications, such as transmitters, receivers, and laboratory equipment. The "MC" series is known for its versatility and rigid construction, featuring silicone-treated steatite insulation and silver-plated phosphor bronze wiping contacts for noise-free operation - Capacitance Range: Typically 10 pF to 140 pF.
Plates: 19 plates.
Characteristic: The "S" suffix denotes a Straight Line Capacity characteristic, meaning the capacitance changes linearly with the degree of rotation.
Voltage Rating: Single-spaced types like the MC-140-S have a nominal air gap of 0.0245" and are typically tested at 1000 V R.M.S. at 60 Hz.
Construction:
Soldered nickel-plated brass rotors and stators.
Rotor shaft supported by bearings at both the front and rear for high stability.
Mounting options include threaded brass front bearings for panel mounting and tapped aluminum end brackets for base mounting - NEW IN BOX
