Description

G.E. Military Surplus Model P7761569PT4, 23-111 pF 4725V Single Section Air Variable Capacitor.

 This capacitor is very heavy duty and weighs over 1 1/2 pounds. It has ceramic stand off blocks attached and included.

Key Specifications (from NSN 5910-00-160-0408 data matching the stamped part number):
  • Capacitance: 23 pF minimum to 111 pF maximum (single section, straight-line capacity). Your measured 25–114 pF is consistent with normal variation, surface condition, or measurement method.
  • Voltage rating: 4725 V AC peak.
  • Plate quantity: 26.
  • Plate spacing: Approximately 1/16″ (matches your observation and supports the high voltage rating).
  • Shaft: 1/4″ diameter round, approximately 1.062″ long.
  • Dimensions: Overall length 5.438″, width 2.750″, height 2.312″ (body length ≈4.125″). Matches your measurements of ~5½″ × 2¾″ × 2⅛″.
  • Construction: Unenclosed air-dielectric, ceramic insulation supports, aluminum alloy plates/frame, 4 unthreaded mounting holes, solder-lug terminals.
  • Rotation: 360° clockwise.
  • Associated manufacturer: General Electric Co. (military surplus part).
These were high-voltage military-spec units designed for RF/transmitter applications requiring robust voltage handling.
