Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are a type of electrolytic capacitor that uses an aluminum foil anode and a liquid or solid electrolyte as cathode to offer large capacitance values in small physical footprint. Capacitance values range from 1µF to over 10,000µF; providing a variety of design options for storage, coupling, and decoupling applications. The UPA0J102MPD1TD is an aluminum electrolytic capacitor from the UPX series by Nichicon, and is a Surface Mount construction with a 1210 size.

Application Field

Aluminum electrolytic capacitors are widely used as a cost effective energy storage solution in electronic systems. The UPA0J102MPD1TD is designed to be used in noise filter, DC-DC converter and DC-AC inverter applications. It is rated for use in temperatures of -55°C to +105°C. The rated voltage is 16V and capacitance is 10µF.

Working Principle

An aluminum electrolytic capacitor is constructed with an anode of etched aluminum foil and a cathode of either wet or dry electrolyte. A thin oxide film is formed on the anode which provides the majority of the capacitor’s equivalent series resistance (ESR) and equivalent parallel capacitance (EPC). The electrolyte acts as an insulator, allowing the charge to be stored in the electrostatic field. The ESR and EPC will vary depending on the properties of both the aluminum foil and the electrolyte.

When a voltage is applied across the capacitor, the anode and cathode are attracted to each other and a current will flow between them. This current sweeps away any impurities from the surface of the aluminum foil, creating a strong electrical field which forms the capacitor’s capacitance. As the current is passed through the capacitor, it can cause the aluminum foil to degrade, leading to reduced capacitance and increased ESR over time. This process is known as polarity reversal, and must be accounted for when designing with electrolytic capacitors.

Safety features

As aluminum electrolytic capacitors can hold a large amount of energy, there is always a risk of electrical malfunctions which can lead to damage to both the device and the user. For this reason, the Nichicon UPA0J102MPD1TD has several safety features built in. These include a solid construction with organic flame retardant coating to reduce the risk of fire or explosive, and a pressure relief valve which slowly releases the stored energy if the capacitor is overcharged or overloaded.

In addition, the UPA0J102MPD1TD comes with an internal resettable fuse which is designed to cut off the power if the capacitor is subjected to abnormal voltage or current. This helps to protect the capacitor from damage and minimize the risk of injury to the user. The fuse can easily be reset for repeated use.

Conclusion

The Nichicon UPA0J102MPD1TD is a versatile and reliable aluminum electrolytic capacitor that is suitable for many noise filter and power applications. Its surface mount construction and robust safety features make it perfect for use in a wide range of systems. Its small size and wide capacitance range make it an attractive choice for designers requiring high capacitance in a small package.
