The difference between CBB21 capacitors and CBB22 capacitors
 

The models of these two capacitors belong to the non-polar polypropylene material (CBB), and there is no obvious difference in essence, but they are different in technical details.

The CBB21 capacitor was born earlier than the CBB22 capacitor. It was a film capacitor first developed by a Japanese capacitor company. It was suitable for the role of coupling circuits and filter circuits in the early days.

With the development of capacitor technology, the improved polypropylene material has extended new circuit functions such as step-down and resonance, but the name CBB21 already exists. CBB (non-polar polypropylene material) 2 (direct current) 1 (radial lead wire), this capacitor is also in line, it can't be called an upgraded version of CBB21, it can only be called a CBB22 capacitor by changing its name.
 

What are the characteristics of CBB21 capacitors?
 

1. It is made of metallized polypropylene film, which is a non-inductive structure, and it is also a non-polar capacitor.
2. Compared with CL capacitors (metallized polyester film capacitors), it has less loss and less internal temperature rise
3. It can withstand high pulse and high current, and some can withstand high frequency 100KHZ (such as CBB capacitors for wireless charging)
4. Little change in capacity, negative temperature coefficient
5. The exterior is encapsulated with epoxy resin Author: KYET Capacitor Knowledge Sharing
 

The function of CBB21 capacitor:
 

CBB21 capacitor belongs to the most commonly used type of plug-in capacitor on the circuit. It has many functions. It is widely used in high-frequency, DC, AC and pulse circuits; it is widely used in high-current occasions.
