Aluminum electrolytic capacitors are some of the most widespread types of capacitors in use today. They are used to store electrical energy and to provide short-term power in many applications. The PSU30015A is one of them, and its application field and working principle will be discussed in this article.

Introduction to PSU30015A

The PSU30015A is an aluminum electrolytic capacitor developed by Panasonic. It boasts a capacitance of 15 μF, a voltage rating of 100V, and a temperature rise of up to 25 °C. Its operating temperature range is from -10 to +70 °C, and its ripple current ratings up to 680mArms. It is also humidity resistant and has a long life expectancy. This capacitor is available in both axial and radial lead formats, and is RoHS compliant.

Application Field of PSU30015A

The PSU30015A capacitor is commonly used in a variety of applications, such as power supplies, AC adaptors, audio amplifiers, control lines, timers, and oscillators. The PSU30015A is also suitable for radio transmitters, remote control, and automation equipment, as it has good temperature characteristics. It is particularly well-suited for high-power applications, such as in motor drives and other switching power supplies.

Working Principle of PSU30015A

An aluminum electrolytic capacitor consists of two electrodes separated by an electrolyte. The aluminum foil acts as one electrode and the other is made from a conductive anode plate. When a voltage is applied to the capacitor, a charge is generated, which in turn causes a reaction to occur in the electrolyte. This reaction increases the number of ions present in the solution, which forms a layer on the anode plate. This layer serves to store the electric charge, and thus enabling the capacitor to function.

The construction of the PSU30015A is such that it uses the electrolyte as a dielectric layer to increase its capacitance. This electrolytic capacitance is maintained across the whole operating temperature range, and allows for higher ripple currents to be passed through it without severe voltage drops. This factor is what makes the PSU30015A capacitor very suitable for high-power applications.

Conclusion

In conclusion, aluminum electrolytic capacitors, such as the PSU30015A, provide a reliable source of power storage and are widely used in many applications today. The PSU30015A in particular is able to offer high current ripple ratings due to its construction. This makes it well-suited for applications that require a lot of power like motor drives and switching power supplies.
