Abstract

The utility model discloses a series chip capacitor, belongs to chip capacitors and aims to provide a chip capacitor which can reduce circuit welding workload and improve circuit reliability. The series chip capacitor comprises at least two chip capacitor cores, each chip capacitor core comprise an anode tantalum block, a tantalum wire fixed on the anode tantalum block, and a cathode layer coating the surface of the anode tantalum block; every two adjacent chip capacitor cores are fixedly and integrally connected through an insulating encapsulation layer and communicated serially through a connecting sheet (6); and a positive leading piece (1) is welded on the tantalum wire (5) of a first chip capacitor core, and the cathode layer (3) of the last chip capacitor core is welded with a negative leading piece (7). The series chip capacitor provided by the utility model enables the circuit to be more compact, and reduces the size and the weight of electronic equipment, and is an integrated type chip connector.

Description

The series sheet type capacitor

Technical field

The utility model relates to a kind of electronic devices and components, relates in particular to a kind of patch capacitor device.

Background technology:Along with the development of electronic equipment to miniaturization, integrated, intelligent, high frequencyization and High Density Packaging direction, market has also proposed the requirement of paster installation, large ripple current-resistant and aspects such as ripple voltage impact, high stable reliability to capacitor.Yet present chip capacitor is single separate component mostly, therefore when constituting series circuit, need some single chip capacitors be welded; This can cause not only that circuit structure is loose, the volume that increases electronic equipment, increase the welding job amount, lower efficiency, but also can cause circuit reliability to descend.

Summary of the invention:To the above-mentioned defective that exists in the prior art, the utility model aims to provide a kind ofly can reduce circuit welding job amount, improve circuit reliability, can make the compact more series sheet type capacitor of circuit structure.

To achieve these goals, the utility model adopts following technical scheme: it comprises by anode tantalum piece, be fixed on tantalum wire on this anode tantalum piece, be coated on the chip capacitor fuse that the cathode layer on said anode tantalum piece surface constitutes; Said chip capacitor fuse has two at least, fixedly is connected as a single entity by insulating sealed layer between each adjacent chip capacitor body and is communicated with through the brace series connection; Be welded with anodal lead-out tablet on the tantalum wire of first chip capacitor fuse, the cathode layer of last chip capacitor fuse and the welding of negative pole lead-out tablet.

Brace and each chip capacitor fuse are sealed by insulating sealed layer is airtight.

Compare with prior art; The utility model is owing to adopted technique scheme; Some single chip capacitor fuses through brace welding and connect as a wholely, are needed the defective that each chip capacitor is welded one by one when therefore having overcome built-up circuit; Not only alleviate the welding job amount, improved production efficiency, and avoided being welded with one by one phenomenons such as the rosin joint that possibly cause, dry joint, improved the reliability of electronic equipment effectively; Moreover, since some single chip capacitor fuses are integrated as a whole, therefore can make the volume and weight that circuit is compact more, reduce electronic equipment.
