The specific differences and characteristics of super capacitors and ordinary capacitors

1. The overview is different:

Overview of supercapacitors: Supercapacitors, also known as electrochemical capacitors , electric double-layer capacitors , gold capacitors , and Farad capacitors , are electrochemical components developed from the 1970s and 1980s to store energy through polarized electrolytes.

Overview of ordinary capacitors: ordinary capacitors are a kind of static charge storage medium, and there may be charges. This is its characteristic. It has a wide range of uses. It is an indispensable electronic component in the field of electronics and electricity.

2. Different features:

Features of supercapacitors: fast charging speed, charging for 10 seconds to 10 minutes can reach more than 95% of its rated capacity; long cycle life, deep charge and discharge cycles can reach 10,000 to 500,000 times, no "memory effect";

The characteristics of ordinary capacitors: large size, small capacity Uses: oscillation, resonance, decoupling and circuits with less demanding requirements. Non-polar monolithic capacitors are smaller in size than CBB, and others are the same as CBB.

3. Different uses:

The use of supercapacitors: Micro- supercapacitors have been widely used in small mechanical equipment during the development of supercapacitors for more than 30 years , such as computer memory systems, cameras, audio equipment and auxiliary facilities with intermittent power consumption. Large-sized cylindrical supercapacitors are mostly used in the automotive field and natural energy harvesting.

Overview of ordinary capacitors: mainly used in power supply filtering, signal filtering, signal coupling, resonance, filtering, compensation, charging and discharging, energy storage, DC blocking and other circuits.
