Aluminum - Polymer Capacitors

Aluminum – Polymer Capacitors, or Polymer Aluminum Electrolytic Capacitors, are growing in popularity due to their unique characteristics and low voltage ratings. The number A700X397M002ATE010 is a particular capacitor and is considered an aluminum – polymer capacitor. Below is a summary of the application field and working principle of the A700X397M002ATE010 and other aluminum – polymer capacitors.

Application Fields

Aluminum – polymer capacitors are typically used in portable electronic devices such as phones and laptops, as well as in some automotive electronics and telecommunications equipment. Due to their low voltage ratings and superior temperature stability, they are preferred in applications where the temperature and voltage of the device can vary greatly, such as those in portable devices that are constantly changing in temperature when used. Additionally, they are resistant to voltage surges generated by spikes in the main supply.

Working Principle

Aluminum – polymer capacitors are created through a process of anodization, which is the oxidation of an aluminum film in an electrolytic bath of a suitable acid. The resulting Anodized layer of the aluminum acts as a dielectric between two electrodes; the anode and the cathode. This dielectric layer acts as an insulator, which is why the current does not pass through the capacitor like it does in a traditional electrolytic capacitor.The two electrodes of the capacitor are separated by an extremely thin layer of dielectric material, typically a layer of aluminum oxide or other metal oxide. This allows the current flow to occur through the capacitor for a brief amount of time. The amount of current that flows through the capacitor is determined by the capacitance value of the capacitor, which is dependent on the size and shape of the capacitor as well as the dielectric material used.

Advantages

Aluminum – polymer capacitors offer a variety of advantages over traditional electrolytic capacitors. They have a wide temperature range, typically from -55°C up to +125°C, allowing them to be used in a variety of applications. Additionally, they have a low impedance over a wide range of frequencies, which gives them good noise suppression at higher frequencies, as well as improved stability at higher frequencies.In addition to this, they are very small in size and light in weight, which makes them well suited for applications where physical size is a major factor. Furthermore, they have a long lifespan and excellent reliability, which makes them a good choice for industrial and military applications.

Conclusion

The A700X397M002ATE010 and other aluminum – polymer capacitors are rapidly growing in popularity due to their unique characteristics and low voltage ratings. They are used in a variety of electronic and automotive applications due to their wide temperature range, low impedance, and small size. They also offer excellent reliability and a long lifespan, making them ideal for industrial and military applications.
