Aluminum Electrolytic Capacitors: UHV0J222MPD Application Field and Working Principle
Aluminum electrolytic capacitors are composed of two aluminum foils and a layer of electrolyte. The two aluminum foils are separated by a paper, plastic or ceramic dielectric material, and a heavy layer of oxidized aluminum is formed on their surfaces. This creates a three-layer plate sandwich structure. The real working part of the capacitor is the electrolyte between the two layers of aluminum foil. Aluminum electrolytic capacitors have the characteristics of low cost, wide capacitance range, high rated voltage and high capacitance.
The application field of UHV0J222MPD stands for "screw-mount aluminum electrolytic capacitor". It is a type of aluminum electrolytic capacitor, which is used in the fields of audio frequency, power supply, radio frequency and disk drive. UHV0J222MPD has a terminal pitch of 8mm, rated voltage of 10V and capacitance of 10uF. The maximum operating temperature is 105℃ and should be placed in the vertical or horizontal direction on a printed board for cooling.
The working principle of UHV0J222MPD relates to capacitance. The capacitance is determined by the linear distance between the two metal foils, the dielectric constant of the medium between them and the surface area of the two metal foils. There is a layer of oxide film on the surface of the aluminum foil and this oxide layer has a very high dielectric constant. This oxide layer plays the role of a dielectric media that produces an electric field between the positive and negative plates of the capacitor. Therefore, when a voltage is applied, a capacitance is generated.
In addition to the application fields and working principles of UHV0J222MPD, some important parameters should also be taken into consideration. The rated voltage indicates the maximum allowable voltage applied to the capacitor, and the capacitance indicates the maximum amount of charge that can be stored in the capacitor. The peak pulse current is the greatest current applied to the capacitor during a short time period. The lifetime is related to the temperature applied on the capacitor and the load applied on it. The ESR stands for equivalent series resistance, and it is mainly related to the internal inductance of the capacitor. It will affect the stability of the capacitor when voltage switching is applied on it.
In conclusion, UHV0J222MPD is a type of aluminum electrolytic capacitor that has wide applications in many fields. Its working principle is based on the electric field between its positive and negative plates due to the high dielectric constant of the oxide layer formed on the surface of the aluminium foil. However, in order to ensure the proper working of UHV0J222MPD, it is also important to consider other important parameters such as rated voltage, capacitance, peak pulse current, lifetime and ESR.
