A filtering capacitor is an energy storage device connected in parallel at the output of a rectifier power

 circuit to reduce AC ripple coefficient and smooth DC output. In electronic circuits that convert AC to 

DC power supply, filtering capacitors not only ensure smooth output of the power supply and reduce

 the impact of AC meter ripple on the electronic circuit, but also absorb the current ripple generated

 during the operation of the electronic circuit and the interference transmitted through the AC power 

supply, making the performance of the electronic circuit more stable.

Filter capacitors are used in power rectifier circuits to filter out AC components. Make the output DC

 smoother. Moreover, for precision circuits, parallel capacitor circuit combinations are often used at this 

time to improve the working effect of filtering capacitors. Low frequency filtering capacitors mainly work 

in the filtering of rectified switching power supplies, with a working frequency of several thousand Hz to

 tens of thousands of Hz. Filter capacitors play a very important role in switching power supplies.

Bypass of Surface mount Electrolytic Capacitors

A surface mount aluminum electrolytic capacitor that can bypass and filter out high-frequency components

in AC signals mixed with high-frequency and low-frequency currents is called a bypass capacitor.

The main function of a bypass capacitor is to generate an AC shunt, thereby eliminating unwanted energy 

that enters the susceptible area. That is, when a signal mixed with high and low frequencies is amplified

 by an amplifier, only the low frequency signal is allowed to enter the next stage when passing through 

a certain stage, and no high frequency signal is required to enter. Therefore, a grounding capacitor of 

appropriate size is added to the input terminal of that stage, so that higher frequency signals can be easily

 bypassed through this capacitor (because the capacitor has a small impedance to high frequencies), while

 low frequency signals are transmitted to the next stage for amplification due to the large impedance of 

the capacitor to it.

Filter out high-frequency components in signals mixed with high-frequency and low-frequency signals 

through electronic components, allowing only low-frequency signals to be input to the next stage. And 

without the need for high-frequency signals to enter, this is bypass.
