​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. The positive electrode is a metal foil. The oxide film close to the metal with the positive electrode is a dielectric. The cathode is composed of conductive materials, electrolytes and other materials. At the same time, the positive and negative of the electrolytic capacitance can not be connected wrong.

The electrolytic capacitors are divided into two types: non polarity and polarity. The non-polar electrolytic capacitors are made of double oxide film structure, similar to the two polar electrolytic capacitors which connect two negative electrodes; The capacitor with polarity usually plays the role of power filter, decoupling, signal coupling, time constant setting, DC isolation and so on in power circuit or medium frequency and low frequency circuit. How to understand the function of high frequency and low resistance Jingmen electrolytic capacitor?

1. The capacity per unit volume is very large, dozens to hundreds times larger than other kinds of capacitance.

2. Rated capacity can be very large and can be easily achieved tens of thousands μ F even a few F.

3. The price is overwhelming over other types, because the composition of electrolytic capacitors is common industrial materials, such as aluminum, etc. The equipment for manufacturing electrolytic capacitors is also ordinary industrial equipment, which can be produced on a large scale and has relatively low cost.

4. The loss and leakage are relatively large.
