Abstract

The invention discloses a foil type electrode organic thin film winding type Y capacitor. The Y capacitor is suitable for power type interference suppression with an organic thin film as a medium and a foil type electrode. The capacitor comprises a pair of electrodes, an aluminum foil layer welded at the lower ends of the electrodes, and an organic thin film layer attached at the lower end of the aluminum foil layer. Two ends of the organic thin film layer are provided with reserved widths relative to the aluminum foil layer, wherein the reserved width far from an electrode lead-outing end is at least 2 mm, and the reserved width close to the electrode lead-outing end is at least 3 mm. According to the Y capacitor, safety requirements can be satisfied, the voltage resistance is high, the structure is simple, and the practicability is strong.

Description

technical field [0001] The invention relates to a capacitor, in particular to a winding type Y capacitor whose electrode is a foil organic film. Background technique [0002] At present, Y-type AC safety capacitors are mainly used in power supply interference suppression occasions or RC components. Usually, the rated voltage is less than or equal to 400V.AC, and the national standard requires the durability test voltage to be greater than or equal to 8KV.DC, so Y capacitors are basically made of ceramics. The dielectric capacitors are mainly ceramic capacitors, and the advantage of ceramic capacitors is their high withstand voltage. The disadvantages are: the capacity is small (basically below 0.1 μf), the capacity changes greatly with temperature, and the capacity drift can reach up to 80% of the rated capacity. In addition, the ceramic capacitor needs to use silver paste as the electrode, and the cost is high. Contents of the invention [0003] In order to solve the abo...
