Description
Technical field
The utility model relates to the improvement technology of capacitor arrangement, is specifically related to the improvement technology of miniaturization structure thin film capacitor structure.
Background technology
Illuminating industry is more and more higher to the requirement of start-up capacitance device, but just more and more miniaturization of volume requirement, traditional paper tinsel formula cascaded structure capacitor satisfies instructions for use in function, but increasing client needs the small size capacitor.Traditional metallization series connection small product size can satisfy customer requirement, but the withstanding current capability of metallic electrode capacitor is poor, and the life-span is short.The life requirements of electricity-saving lamp is more and more higher, therefore the reliability of electronic product is proposed requirements at the higher level.
The utility model content
The utility model provides a kind of miniaturization structure film capacitor, and the utility model has solved the problem that miniwatt energy-saving lamp start-up capacitance reliability is low, the life-span is low, volume is excessive.
The utility model provides a kind of employing aluminium foil and metallized film coating to make electrode, the high voltage startup capacitor, and the effective area of electrode increases.Medium separates between aluminium foil, improves flashover voltage.This kind capacitor withstanding current capability is strong, good heat dissipation, highly reliable, withstand voltage height, high accuracy, safety and environmental protection, can use under the occasion of high pressure, high-frequency heavy-current.
For addressing the above problem, the utility model adopts following technical scheme: the miniaturization structure film capacitor comprises two lead-in wires, capacitor body and bodies; Described intrinsic capacitor body comprises three layers of medium, at orlop medium medial surface layer of metallized film is arranged, be respectively arranged with aluminium foil above the two layer medium in addition, the aluminium foil edge part extend out to medium side along the outside, aluminium foil and layer of metallized film are as electrode, medium and electrode roll have gilding layer at the aluminium foil outer edge, the gilding layer connecting lead wire around the body of package formation capacitor.
The high-frequency loss of the utility model capacitor is little, and it is little self to heat up, and temperature capacity is strong, and dielectric behavior is stable, also has stronger moistureproof ability and resisting temperature impact capacity.Can under 100 ℃ of-110 ℃ of operational environments, work for a long time again.This kind capacitor life-span is long, highly reliable, safety and environmental protection, can use under the occasion of high pressure, large electric current, volume requirement miniaturization.
