Good Insulation Resistance CBB21 475J 630V Metallized Polypropylene Film Capacitor Good Insulation Resistance
There are indeed many names for CBB21 capacitors. In addition to being called CBB21 capacitors, they are also called CBB22 capacitors. Some manufacturers also like to call them MPP capacitors. They are actually exactly the same, referring to metallized polypropylene film capacitors.
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
