UPJ1V151MPD6TD Capacitors

Aluminum electrolytic capacitors are an essential component in power electronic circuits, largely due to their high capacitance values in relatively small packages. One such electrolytic capacitor is the UPJ1V151MPD6TD capacitor, which offers enhanced thermal performance and noise insulation in a range of STMicroelectronics applications. This article will discuss the UPJ1V151MPD6TD’s application field and working principle.

Application Fields

The UPJ1V151MPD6TD is available in surface-mount packages ranging from 6.3mm to 18mm, and acts as a miniature power reservoir that is able to store and deliver energy within a short time frame. This makes it suitable for use in applications such as motor control, power factor correction, audio frequency transmission, digital circuits, and cameras, where high current pulses are required. The UPJ1V151MPD6TD also offers improved reliability in respect to its equivalent predecessors, thus making it suitable for use in a range of automotive applications.

Working Principle

Unlike conventional film capacitors, the UPJ1V151MPD6TD utilizes an electrolytic technique for its construction. This technique involves an aluminum-oxide film that is formed on the anode. This oxide layer acts as an insulator between the electrolyte and the anode, thus enabling a large capacitance per unit volume. The aluminum foil used during the construction of the UPJ1V151MPD6TD is thermally etched, which enables it to generate an additional airflow that increases the capacitor’s thermal performance. This particular electrolytic capacitor is polarized, meaning that it must be connected with the correct polarity otherwise the capacitor could be damaged.

Conclusion

The UPJ1V151MPD6TD is a miniature aluminum electrolytic capacitor that offers enhanced thermal performance and noise insulation. It is well suited for use in applications such as motor control, power factor correction, audio frequency transmission, digital circuits, and cameras, and also offers improved reliability in automotive applications. It utilizes an electrolytic technique that involves an aluminum oxide film on the anode acting as an insulation layer, and has a polarized construction which must be respected in order to prevent damage.
