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
