This paper mainly introduces the electronic character and parameters;through comparing with common Aluminum Polymeri- zer Electrolysis Capacitor,low ESR Aluminum Polymerizer Electrolysis Capacitor and tantaium Aluminum Polymerizer Electrolysis Ca- pacitor,the advantage of low ESR and high ripple current is discussed;The peculiarity of application in current is stated.

According the calculated results by theoretic formula and based on the measured data in experiments, electrolytic paper and forming foil have a strong effect on ESR.

ELECTRONIC COMPONENTS & MATERIALS (China), Vol 19, No 2, P 15 16,21 (Apr 2000) In Chinese Three methods for testing static capacitance are presented They are time constant method, constant current charge method and constant current discharge methods The first one is simpler and the other two are more accurate The methods for testing ESR and leakage current are also presented (4 refs

This compensation circuit can make the stability of the LDO linear regulator undependent on the effect of load capacitor s equivalent serial resistance(ESR),and it also makes the unit gain frequency bandwidth change slightly when the load is varying,thus greatly improving the performance of transient response.

In addition, some methods to calculate equivalent series resistance (ESR) are analyzed and compared.

The power dissipation of equivalent series resistance and its influence on lumen efficiency of GaN based high power light-emitting diodes;

The design and process technology in order to decrease equivalent series resistance are discussed during multilayer ceramic producing.
