Abstract
The invention discloses a wave-cut edge T-shaped film for a metallized capacitor, and relates to the technical field of capacitors. The wave-cut edge T-shaped film comprises a thin film body. Metal strips are plated to form a plurality of independent T-shaped structures on the surface of the thin film body. The wave-cut edge T-shaped film is characterized in that the connecting edge of the thin film body is wavy; the thin film body is a polypropylene thin film; and the metal strips are zinc-aluminum alloys. The wave-cut edge T-shaped film is more rational in structural design; and by the wave-cut connecting edge, the contact area of the capacitor can be enlarged, equivalent series resistance can be lowered, heat is reduced, and the wave-cut edge T-shaped film is higher in high-frequency performance and longer in service life.
Description
Technical field:
The present invention relates to the capacitor technology field, the wave that relates in particular to a kind of metallized capacitor divides side cut T type film.
Background technology:
Energy-saving and frequency-variable full-solid-state minisize intermediate frequency, high frequency, superaudio induction heating equipment.Heating, the heat treatment gas that high power switching power supply and Special Automatic control system etc. are widely used in aviation, military project manufacturing, non-ferrous metal quenches, wide spectrums such as annealing is modified, soldering, forge hot, standard component production, machine-building have obtained widespread usage, are the energy-conserving and environment-protective products that present country widelys popularize.Adopt special power component and unique inversion transformation technique, the output frequency of oscillation reaches as high as 400KHZ, is particularly suitable for the Fast Heating of micro metal article etc.: output hunting power 20～160KVA; Output frequency of oscillation 30～150KHz; Output oscillating current 200～2000A.The crucial series resonance capacitor supporting with it with these HF induction heating apparatus obtained good development space and opportunity, all has than big-difference with regard to its design, technology, quality level.
For adapting to the condition of work of high frequency, high pressure, big electric current; Must adopt low ESL and low ESR technology; Its core is exactly an appropriate design, reduces fuse (element) inherent inductance as possible, eliminates the inductance between fuse and fuse, makes equivalent series inductance ESL be issued to minimum in limited condition; Reduce the path that high-frequency current is flowed through, increase the sectional area that electric current is flowed through, reduce high-frequency current density, make equivalent series resistance ESR drop to minimum in limited condition.
Summary of the invention:
Technical problem to be solved by this invention is to overcome the defective of prior art, provides a kind of wave that reduces the metallized capacitor of equivalent series resistance to divide side cut T type film.
Technical problem to be solved by this invention adopts following technical scheme to realize.
A kind of wave of metallized capacitor divides side cut T type film, comprises thin-film body, and thin-film body is coated with bonding jumper on the surface, and bonding jumper is plated to a plurality of separate T type structures, and it is characterized in that: the fillet of said thin-film body is arranged to waveform.
Said thin-film body is a polypropylene film.
Said bonding jumper is an allumen.
Open failure is accomplished explosion-proof task after leaning on microfuze to fuse between the bonding jumper of T type structure, and its responsiveness is very fast, and is explosion-proof reliable.
Structural design of the present invention is more reasonable, and the fillet that wave is cut can increase the contact area of electric capacity, reduces equivalent series resistance, reduces heating, and high frequency performance is better, longer service life.
