Current, in electroanalysis capacitor industry basically electroanalysises with aluminium capacitor and Tantalum electroanalysis capacitor is given priority to, think aluminium electroanalysises normally capacitor is in the respect such as dependability, high frequency function relatively tantalum electroanalysises capacitor is poor, accordingly, aluminium electroanalysises capacitor is used at dependability to ask commonly not tall circumstance. Because tantalum electroanalysises the capacitance of capacitor is bigger and bigger, volume is minorrer and minorrer, have impedance at the same time low, leakage current is high frequency and small, characteristic good wait for a characteristic, applied range is accordingly wider and wider, crop also is able to promote quickly.

Piece type Tantalum electroanalysises capacitor holds the mainstream

At present global Tantalum electroanalysises the output year after year of capacitor increases by degrees, by 11 billion of 1995, add reach 18 billion of 1998, 21 billion of 1999, 24 billion of 2000, 27 billion of 2001, 31 billion of 2002 reach 35 billion of 2003. 1995 - between 2000, tantalum electroanalysises the annual growth rate of capacitor is 16.9% , 2000 - it is between 2003 13.4% .

Our country Tantalum electroanalysises capacitor is the state that carried high speed development more, output of the company inside the system increases one billion two hundred and forty-seven million eight hundred and ninety-seven thousand of 2003 from two hundred and seventy-one million five hundred and fifty-six thousand of 1997, annual growth rate is 28.94% ; Sales volume increases one billion two hundred and sixty-eight million seven hundred and sixty-seven thousand of 2003 from two hundred and twenty million six hundred and thirty-three thousand of 1997, year all grow 33.85% .

As electronic product direction portable, piece product requirement quantity increases type stage by stage. Traditional down-lead Tantalum electroanalysises the market demand year after year of capacitor drops, piece type Tantalum electroanalysises the market demand of capacitor criterion year after year grows. The whole world piece type Tantalum electroanalysises the crop of capacitor already by 7.9 billion of 1995, piece type is changed rate 71% , development goes to 19 billion of 2000, piece type is changed rate 80% , current piece type is changed rate already exceeded 90% .

Domestic Tantalum electroanalysises a type of capacitor change a course quite fast also. The enterprise inside the system piece one billion and forty-four million three hundred and sixty-five thousand when tantalum crop increases to 2003 by seventy-five million nine hundred and twenty-six thousand of 1997, annual growth rate is more than 54% , piece type is changed rate also by 1997 27.96% rise 2003 83.69% .
