UZT1A220MCL1GB Capacitors

Aluminum electrolytic capacitors are one of the most common and important types of capacitors used in most electrical appliances and electronics. UZT1A220MCL1GB is a type of aluminum electrolytic capacitor of which the application field and working principle will be discussed in this article.

Overview of Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are polarized capacitors which are made of two aluminum foils that are separated by a paper wound separator. The negative aluminum foil, referred to as the anode, is filled with an electrically conductive liquid electrocatalyst called the electrolyte. The surface of an anode is coated with an insulating oxide film which provides the desired capacitance of the capacitor. The second electrode, the cathode, which is formed from a second aluminum foil, is then spaced away from the anode and connected to the substrate either directly or indirectly.

The electrolyte additionally contains oxidizing agents, reducing agents, and other chemicals which help prevent oxidation of the anode, thus maintaining the desired capacitance over time. The electrolyte also provides a current exchange path between the anode and the cathode. Aluminum electrolytic capacitors can provide high capacitance densities ranging from 1 µF to 100 µF and operating temperature range from -40°C to +125°C. Since aluminum electrolytic capacitors are primarily designed for low-frequency applications, their use is limited for high-frequency and signal applications.

UZT1A220MCL1GB Working Principle

UZT1A220MCL1GB is a aluminum electrolytic capacitor with 220µF capacitance at 6.3V rated voltage and a −40+105℃ operating temperature range. It is a single-ended aluminum electrolytic capacitor suitable for high-frequency DC filter applications. It is a miniature solid electrolytic capacitor with a 5mm wide and 10mm long case and a rated ripple current of 2.6A.

UZT1A220MCL1GB aluminum electrolytic capacitor utilizes a solid electrolyte instead of traditional liquid electrolyte, which improves capacitance properties while reducing leakage current and resistance. The solid electrolyte is made with a special ceramic material which has reliable performance, better temperature stability and long life. The electrolyte also provides a current exchange path between the anode and the cathode. In addition, UZT1A220MCL1GB aluminum electrolytic capacitor has a low ESR (Equivalent Series Resistance) rate of 0.47Ω, which improves the current conduction capability of the capacitor.

Application

UZT1A220MCL1GB aluminum electrolytic capacitors can be used for various applications including automotive, DC motor drives, medical, power supplies, switching power supplies and other general purpose applications. For example, The UZT1A220MCL1GB can be used in DC motor control circuits, where it dissipates the heat generated by the motor’s current, or can be used in automotive, to filter high-current circuits, such as the 12V auxiliary power supplies, which minimizes the ripple in the output of the circuit.

In addition, UZT1A220MCH1GB aluminum electrolytic capacitor can also be used in power supplies, to store and release energy in the shortest time. Its low ESR rate helps reduce the power loss of the power supply. Furthermore, UZT1A220MCL1GB aluminum electrolytic capacitor can also be used in switching power supplies, to filter the input current, which reduces the ripple components of the current, and thus the “noise” in the power supply.
