Description

Hammarlund HFC-50-B, 2 to 40 pF 3000 Volt Single Section Air Variable Capacitor

Key Specifications:
  • Brand: Hammarlund
  • Model: HFC-50-B (marked on frame; also consistent with HFA-50 series)
  • Sections: 1 (single-section)
  • Capacitance: 2 pF minimum to 40 pF maximum
  • Plate spacing: Approximately 1/16 in (0.0625 in)
  • Estimated voltage rating: ~3000 V peak (standard ARRL Handbook guideline for ~0.060–0.065 in air-gap spacing; practical RF rating for moderate-power transmitting or neutralizing use)
  • Shaft: 1/4 in diameter
  • Dimensions (approx.): Length 3-3/4 in, Width 3 in, Height 2-1/4 in
  • Construction: Classic Hammarlund multi-plate air-dielectric design with ceramic insulators, metal frame, and “HAMMARLUND MFG. CO. INC. NEW YORK MADE IN U.S.A.” markings. Wider plate spacing for higher voltage capability.
Exact factory voltage for this specific wide-spaced variant was not located; the rating is derived from the measured plate spacing.
