Teardrop Plate Air Variable, 9-265 pF

Part Number:
(CAV) 256

Product Details:
This is a capacitor where the capacitance is changed by varying the overlapping area of metal plates, with air serving as the dielectric.
The "teardrop" shape refers to the specific form of the metal plates within the capacitor. This shape is not just for aesthetics; it often serves a functional purpose.

  • The shape can influence the linearity of the capacitance change as the plates rotate. This can be important for certain tuning applications.
  • The shape of the plates will determine the rate of capacitance change as the shaft is turned. Teardrop shapes are used to achieve specific capacitance curves.
  • The shaping of the plates can also affect the voltage breakdown characteristics of the capacitor.
    • Air variable capacitors with teardrop plates are most often found in radio frequency circuits, in older radio equipment, and also in test equipment.
