2. The Most Common Type of Capacitor: MLCC
Currently, the most widely used capacitor in the market is:
MLCC (Multi-Layer Ceramic Capacitor)
Characteristics:
Small size
Low cost
High stability
Extremely large usage volume
They are widely used in many applications, such as:
Smartphones
Computers
Automotive electronics
Industrial equipment
Some electronic devices contain hundreds or even thousands of capacitors internally.
