High frequency low resistance electrolytic capacitance is one of the capacitors. The physical definition is a discrete component composed of two conductive plates with dielectric characteristics in the middle. The electrolytic capacitance is divided into positive and negative polarity.

​How to remove solid state capacitance? What is it? Solid state capacitor is called solid aluminum electrolytic capacitor. It is different from ordinary capacitors (liquid aluminum electrolytic capacitors) in that it uses different dielectric materials. The dielectric material of liquid aluminum capacitors is electrolyte, while the dielectric material of solid capacitors is conductive polymer.

​Aluminum capacitor is a kind of energy storage element, which is used in circuit for tuning, filtering, coupling, bypass, energy conversion and delay. Capacitors are usually called capacitors. According to its structure, it can be divided into fixed capacitor, semi variable capacitor and variable capacitor. It is a kind of universal electrolytic capacitor with good electrical performance, wide application range and high reliability made of aluminum.

​Electrolytic capacitors are widely used in different fields of power electronics, mainly for smoothing, energy storage or filtering after AC voltage rectification, and also for non precision timing delay. In the MTBF prediction of switching power supply, the model analysis results show that electrolytic capacitor is the main factor affecting the life of switching power supply, so it is very important to understand and influence the factors of capacitor life.

Discharge the capacitance two pins by using a pointer multimeter, and connect the positive pole of the electrolytic capacitor with the black probe of the multimeter. The red probe is connected to the negative pole (for the pointer multimeter, the probe is adjusted mutually when measured with the digital multimeter). Normally, the probe shall swing in the direction of small resistance, and then return to infinity gradually.
