Description

Air Variable 9.5 to 12.5 pF, Wide Space 9000 Volt Single Section Air Variable Capacitor

Key Specifications:
  • Brand: Unmarked / unknown
  • Model: Unknown
  • Sections: 1 (single-section)
  • Capacitance: 9.5 pF minimum to 12.5 pF maximum
  • Plate spacing: Approximately 1/4 in (0.25 in)
  • Estimated voltage rating: ~9000 V peak (standard ARRL Handbook / Radio Handbook guideline for 0.25 in air-gap spacing)
  • Shaft: 1/4 in diameter (brass, slotted)
  • Dimensions (approx.): Length 3-3/4 in, Width 2-5/8 in, Height 2-3/4 in
  • Construction: Wide-spaced multi-plate air-dielectric design with ceramic insulators, few large plates, and sturdy frame. Typical of high-voltage neutralizing, transmitting, or RF trimmer capacitors intended for elevated RF voltages.
Exact original brand and model were not identified; the voltage rating is derived from the measured wide plate spacing.
