Ceramic capacitor characteristics in the circuit

1. Small size. Ceramic capacitor structure is simple, the size can be done very small, 0402 or even 0201 package ceramic capacitor is widely used in mobile phones such as the size of the strict requirements of the occasion.

2. The electrical performance is stable and the temperature has little effect.

3. ESR, ESL value is very low, since the self-resonant frequency is high, it can be applied to the filtering requirements of a few MHz to 1 GHz on the PCB.

4. Due to the structural characteristics of multiple layers and the reasons for packaging, poor resistance to bending, PCB bending deformation may cause capacitor cracking failure.

Based on the above device characteristics, in addition to the filtering scene, the ceramic capacitor is also widely used in applications such as blocking, coupling, and bypassing.
