Aluminum - Polymer Capacitors

Capacitors are an important part of almost every circuit. This includes aluminum-polymer capacitors, which are studied in this article.

Product Overview

The 94SVPD825X0035E7 is an aluminum-polymer capacitor. It is a surface-mount device with an ultra low ESR and high capacitance. It has an operating temperature range of -55°C to +105°C and a rated voltage of 16V. This type of capacitor is especially well-suited for high-frequency applications since it\'s self-healing properties reduce EMI interference.

Application Fields

The 94SVPD825X0035E7 is ideal for high-frequency applications. It is especially useful in applications that require a combination of low ESR, high capacitance, and temperature tolerance. Common applications include power supplies, motor drives, voltage regulators, factor correction circuits, and other DC-DC converters.

Working Principle

An aluminum-polymer capacitor is based on the principle of electrolytic capacitance, which is the capacitance formed between two conductors (conductors in an electrolyte solution). The two conductors are separated by a dielectric material, in this case, a semi-permeable polymer layer. This polymer layer acts as a barrier, preventing ions and electric current from crossing it. As a result, the aluminum-polymer capacitor stores a charge between the two conductors.

The semi-permeable polymer layer also allows for the adjustment of ion concentration in the electrolytic solution, which in turn changes the capacitance. This allows aluminum-polymer capacitors to have a much higher capacitance compared to other types of capacitors.

Advantages

The major advantage of aluminum-polymer capacitors is their very low ESR and high capacitance values. Since they are based on the principle of electrolytic capacitance, they also have excellent temperature tolerance and self-healing properties.

Aluminum-polymer capacitors are also much smaller than their traditional electrolytic counterparts, making them ideal for space-constrained applications. Moreover, their resistive-dielectric material allows for a higher operating frequency, resulting in improved power efficiency.

Disadvantages

The major disadvantage of aluminum-polymer capacitors is their higher cost compared to other types of capacitors. Furthermore, they are not as rugged as some other types of capacitors and may suffer from higher levels of leakage current.

Conclusion

Aluminum-polymer capacitors are an ideal solution for high-frequency applications. The 94SVPD825X0035E7 is an example of such a capacitor, with a combination of ultra-low ESR and high capacitance. It is well-suited for use in power supplies, motor drives, voltage regulators, factor correction circuits, and other DC-DC converters.

Despite their advantages, aluminum-polymer capacitors are more expensive than other types and are not as rugged as some traditional electrolytic capacitors. Therefore, careful consideration should be taken before selecting a capacitor for a particular application.
