Description

National Dual Section 10 to 105 pF 1000 Volt Air Variable Capacitor

 

Key Specifications:
  • Brand: National
  • Model: Unknown
  • Sections: 2 (dual-section / 2-gang)
  • Capacitance: 10 pF minimum to 105 pF maximum per section
  • Plate spacing: Approximately 1/64 in (0.0156 in)
  • Estimated voltage rating: ~1000 V peak (standard ARRL Handbook guideline for ~0.015 in air-gap spacing; practical RF rating for receiving/low-power use)
  • Shaft: 1/4 in diameter
  • Dimensions (approx.): Length 3-1/2 in, Width 2-1/2 in, Height 2-5/8 in
  • Construction: Compact National dual-section air-dielectric design with multi-plate rotors and stators on a common shaft, ceramic terminal strip, and metal frame. Typical of mid-century receiver-style ganged tuning capacitors.
Exact original model number and factory voltage data were not located; the voltage rating is derived from the measured plate spacing.
