Variable capacitor |
摘要 |
A variable capacitor, wherein at least one of its stator or rotor electrode is made of aluminum alloy or copper alloy and coated with a thin dielectric material layer containing fluorocarbon resin as its principal component by means of baking, is disclosed. The disclosed variable capacitor is particularly suited for a miniaturization of an appliance which adopts this variable capacitor. Careful qualification of the electrode materials, dielectric material, additional dielectric substance, and conditions for performing the baking and layer forming operation prevent the formation of the oxide film over the surface of the electrode material, and thus ensures a firm adherence of the layer to the substrate and a large maximum capacitance of the layer.
