High Insulation Low Loss CBB21 223J 400V Metallized Polyester Film Capacitor High-Frequency Resistance​

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

What are the characteristics and functions of CBB21 metal film capacitors?

1. High-frequency resistance, and high-frequency loss is very small, much smaller than CL metallized polyester film capacitors, high reliability, good stability, and long life.
2. The internal temperature rise is small, the high temperature resistance is 105°C, and the high temperature resistance performance is good. (It should be noted that there are many CBB21 capacitors on the market that cut corners. They use poor materials and can only withstand high temperatures of 85°C)
3. High insulation resistance, it has good self-healing properties, of course, this is also a common feature of most film capacitors.
4. The exterior is encapsulated with epoxy resin. If you want to use it in some harsh environments, you can also choose MPB capacitors. Its internal core is the same as that of CBB21 capacitors, but the exterior is sealed with a plastic shell.

Usage:

Suitable for DC and lowpulse occasions, forthe amplifier, TV, communications, power supply, LED drivers and other requirements of the small size of the circuit.

What are the reasons why the CBB21 capacitor burns out?

1. Bought low-quality capacitors
Now the cost of CBB21 capacitors produced by different manufacturers is actually very small. If the price of CBB21 capacitors you buy is obviously lower than the market average price, the possibility of buying inferior capacitors is very high. The materials used for this inferior capacitors are very poor. If the production process can be saved, the performance cannot be guaranteed, and the capacitor with too poor quality is definitely easy to burn out.
2. The working environment temperature is too high
Even a CBB21 capacitor with excellent quality is easy to burn out if the working environment temperature is too high. Generally, the temperature resistance of CBB21 capacitors is -40°C~105°C. Although it can withstand 105°C in theory, its working temperature is higher. High, the life of CBB21 capacitors is drastically reduced.
Generally, a qualified CBB21 capacitor burns out, which is basically caused by too high ambient temperature, such as being too close to an electronic component with a large heat generation (such as a MOS tube), or the entire circuit has a large heat dissipation, and the heat cannot be discharged smoothly. etc., are the core reasons for the damage of CBB21 capacitors.
Excessive operating temperature is one of the most common and most likely causes of CBB21 capacitor damage.
3. Improper selection of capacitors
For example, the current is too large, exceeding the working current of the CBB21 capacitor; the voltage in the circuit is too high, exceeding the rated working voltage of the CBB21 capacitor, etc. If the type is not selected properly, the CBB21 capacitor will be easily damaged during operation.
