We all know that surface mount aluminum electrolytic capacitors have many functions, including

 suppression and anti-interference. Placed in a circuit, such a function cannot be underestimated. 

Some of the mobile phones and computers we use now usually have filtering, coupling, and bypass

 functions on the circuit. There are still some high-frequency and low resistance surface mount aluminum 

electrolytic capacitors available now. Let's first talk about the filtering of the surface mount aluminum 

electrolytic capacitor.As the name suggests, filtering is the operation of removing specific frequency bands from a signal. 

It is mainly used in electronic products such as LCD TVs, which rely on signal frequency for reception. 

The requirements for surface mount aluminum electrolytic capacitors in electronic products are relatively 

high.

Energy storage function of surface mounted aluminum electrolytic capacitors

Due to the energy storage function of reactive components in circuits, parallel capacitors can store 

some energy when the voltage supplied by the power supply increases, and release the energy when

 the power supply voltage decreases, making the load voltage relatively smooth. Capacitor C has a 

smoothing effect; The inductor L connected in series with the load stores energy when the current 

supplied by the power supply increases (caused by an increase in power supply voltage), and releases

 energy when the current decreases, making the load current BI relatively smooth, that is, the inductor

 L also has a smoothing effect. The energy storage function of surface mounted aluminum electrolytic

capacitors plays a significant role in assisting other electronic components in the circuit.

Coupling of Surface mounted Aluminum Electrolytic CapacitorsThe coupling function of surface mount aluminum electrolytic capacitors is to transmit AC signals from

 the previous stage to the next stage. There are also direct coupling and transformer coupling methods 

for coupling. Direct coupling has the highest efficiency and the signal is not distorted, but the adjustment

 of the working points of the front and rear stages is relatively complex and interrelated. In order to ensure 

that the working point of the subsequent stage is not affected by the previous stage, it is necessary to 

separate the previous stage and the subsequent stage in terms of DC, while also allowing the AC signal 

to be smoothly transmitted from the previous stage to the subsequent stage. The method to accomplish

 this task is to use capacitor transmission or transformer transmission. They can both transmit AC signals 

and block DC, so that the working points of the front and rear stages are not interconnected. But the 

difference is that when using capacitors for transmission, the phase of the signal needs to be delayed,

 while when using transformers for transmission, the high-frequency components of the signal need to 

be lost. In general, capacitors are commonly used as coupling elements for small signal transmission, 

while transformers are commonly used as coupling elements for large or strong signal transmission.
