CBB21 105J 400V P15MM Metallized Polypropylene Capacitors Good Moisture Resistance

Good Moisture Resistance CBB21/22 105J 400V  P15MM Metallized Polypropylene Film Capacitor Good Self-Healing Property ​
 

CBB21 can be understood as a reduced version of CBB21 capacitor, and it can also be called ultra-compact CBB21 capacitor, because in the actual circuit use, some circuits have strict requirements on the size of the capacitor, and need to use a small size and high precision capacitor. At this time, it is possible to use CBB21X capacitors.

CBB21 belongs to metalized polypropylene film capacitor, which is characterized by low high frequency loss, excellent for high frequency and high current, high insulation resistance and long life, widely used in high frequency, DC, AC and pulse circuits... With excellent frequency and temperature characteristics, the loss is extremely small even at high frequency, vacuum impregnated with paraffin wax, high insulation performance and good moisture resistance. Suitable for high frequency and high current fields such as color TV S correction circuit, widely used in high frequency, DC, AC and pulse circuits, also used in high end energy saving lamps, brackets, ballasts and other products.

Product features of CBB21:

1. Small size, installation does not occupy space.
2. Metallized polypropylene film, non-inductive structure, excellent electrical performance.
3. Excellent frequency and temperature characteristics. 4.
4. Good self-healing performance. 5.
5. wide operating temperature range.

Role of CBB21 metal film capacitors:

Among all CBB capacitors, CBB21 capacitor can be said to be the most used one. It is mostly used in various DC, pulse, AC step-down and high frequency high current occasions. Especially, it is widely used in energy-saving lamps and electronic ballasts.
