Low Loss CBB21 334J 630V Metallized Polyester Film Capacitor Very
Small Inner Temperature Rise
The naming of CBB capacitors, CBB capacitors, also known as
polypropylene film capacitors, or metallized polypropylene film
capacitors, referred to as metal film capacitors. Commonly used
code names are CBB21 capacitors, CBB22 capacitors, MPR capacitors,
MPP capacitors and so on. Everyone has different names for CBB
capacitors, but they are all the same in essence. They are all
capacitors made of polypropylene film! It is made of metallized
polypropylene film as the medium and encapsulated with epoxy resin.
The material and process of CBB capacitors determine that it has
the characteristics of small size, large capacity, stable
performance, high reliability, and self-healing properties.
Therefore, it is widely used in various LED lighting, home
appliance control boards, instruments and meters, and is used in
circuits such as filtering, resonance, coupling, and
resistance-capacitance step-down.
Features and Usage
1) This is constructed from metallized polypropylene film
dielectric, non-inductive construction.
2) Epoxy resin coating, radial CP wire.
3) Very small dissipation factor at high-frequency, very small
inner temperature rise.
4) Good stability of capacitance, excellent insulation resistance
property.
5) excellent self-healing property.
6) suitable for DC, pulse, high-frequency large-current application
widely used in display, sound equipment, audio-visual devices,
telecommunication equipment, data transmission and process facility
and various electronic equipment.
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.
