Air Variable Capacitor , 4 Section 14-265 / 10-134 / 12-265 / 12-136 pF Mil Spec

Key Specifications & Information
  • Markings: W 5225 and 5208-2 (stamped on the frame/end plates). Manufacturer not clearly identified from markings; appears to be a commercial or military-style multi-section unit.
  • Type: 4-section (4-gang) air dielectric variable capacitor.
  • Capacitance:
    – Section 1: 14 pF min to 265 pF max
    – Section 2: 10 pF min to 134 pF max
    – Section 3: 12 pF min to 265 pF max
    – Section 4: 12 pF min to 136 pF max
  • Plate spacing: 1/64 inch (≈ 0.0156 inch)
  • Shaft: 3/8-inch diameter
  • Dimensions: Length 6¼ inches, Width 3¼ inches, Height 2¾ inches
  • Construction: Metal frame with multiple stator terminals, dual-bearing support, typical rugged multi-gang design for receiver front-end or multi-band tuning applications.
Voltage Rating: Approximately 1000 V peak (based on the 1/64-inch air gap). Close-spaced plates of this type are typically rated in the 600–1000 V range and are suited for receiving circuits or low-power RF use.This is a versatile 4-section tuning capacitor ideal for multi-band receivers, TRF sets, or experimental RF projects requiring independent or paralleled sections.
