Aluminum electrolytic capacitors, commonly known as aluminum electrolytic capacitors, are the most commonly used capacitors in electronic components. The capacitor identified by "UHD1A221MED" is a typical product of this series. Let\'s take a look at its application field and working principle.

Application field of UHD1A221MED Aluminum Electrolytic Capacitors

The UHD1A221MED aluminum electrolytic capacitors are generally used in the power supply and filter circuit of various electronic electronic products. In the power supply circuit, it is used as a filtering effect to reduce the input ripple and noise, thus improving the power efficiency. In radio circuits, its capacity determines how many radio frequencies will get through the device, so it also plays a filtering effect. In addition, aluminum electrolytic capacitors are widely used in three-phase power boards, light-emitting diode boards, frequency dividers, adapters, switches, etc.

Working principle of UHD1A221MED Aluminum Electrolytic Capacitors

The UHD1A221MED aluminum electrolytic capacitors use the electrolyte to form a polarized dielectric. Its construction consists of two parallel metal plates, one of which is the dielectric and the other is the cathode. Through the polarizing action of the electrolyte, the anode is attracted to the diaphragm and the cathode is attracted to the other metal plate. Between the two plates, an electric field of electric energy is formed.

When an AC voltage is applied to the capacitor, the anode and cathode attract ions from the electrolyte, and at the same time, the applied voltage causes the anode to drop, shutting off the current path and creating a capacitance. This is because the capacitance is proportional to the amount of ions located in the series. In this way, a certain amount of current flows through the capacitor.

The UHD1A221MED aluminium electrolytic capacitors have the advantages of small size, stable performance, large capacitance, high load capacity, low price,etc. It is widely used in various types of electronic equipment, and plays an important role in maintaining the normal operation of the electronic equipment. Therefore, it is an important type of component of capacitor in the application of electronic equipment.
