Tantalum - Polymer Capacitors

T52E5476M035C0070 is a type of capacitor, specifically a tantalum - polymer electrolytic capacitor. This type of electrolytic capacitor is polarized – meaning that a voltage is applied to either the anode or the cathode of the capacitor to allow electric current to flow through it. Unlike other types of electrolytic capacitors, tantalum - polymer capacitors are especially useful because they have an extremely high capacitance in an extremely small form factor.

Application Field

Tantalum - polymer electrochemical capacitors have a wide range of applications. Most notably, they can be used in mobile phone electronics to act as a filtering capacitor. This is because they have an extremely low ESR (equivalent series resistance), meaning they can be used as a power reserve when applied in a circuit to defer current changes and voltage spikes. In addition, they can also be used in circuits to hold a trickle current and protect against power surges.

Tantalum - polymer capacitors are also sometimes used in electronic systems for signal conditioning. This is because of their clear role in aiding the performance of the analog front end, which reduces noise from unwanted frequencies as well as increases the sharpness of the signal. As such, they are often used in oscillators, signal converters and amplifiers.

Furthermore, these capacitors often find themselves in use in portable electronics. This is because of their ability to filter and protect against power surges and provide power backup, in addition to the fact that they are relatively small so they do not take up much space.

Working Principle

Tantalum - polymer capacitors work in a very similar manner to other electrolytic capacitors; however, they have several distinct advantages. What sets them apart is their use of a tantalum nitride dielectric. This material requires a very low voltage rating, which reduces power consumption and saves space. As a result, the capacitor is able to store significantly more electrical energy than other, similar capacitors.

In terms of the construction of this type of capacitor, the end-plates are typically made of tantalum and the electrolyte is usually a polymer. The capacitor is then sealed encapsulated dielectric, typically a polymeric material. This forms the basic structure of the capacitor.

The typical working principle of the capacitor involves applying a voltage to the anode or the cathode of the capacitor. When this happens, electrons flow from the negative terminal to the positive terminal of the capacitor, thus allowing current to flow.

This type of capacitor is unique in that it is able to store more electrical energy than other similar sized capacitors, making it ideal for use in a variety of applications. In addition, its construction allows the capacitor to have a very low ESR, which further enhances its usefulness.

Conclusion

T52E5476M035C0070 is a type of tantalum - polymer electrolytic capacitor. Its unique construction allows it to have a very high capacitance in an extremely small form factor, making it ideal for use in a wide range of applications, from filtering capacitors in mobile phones to signal conditioning in oscillators, signal converters, and amplifiers. This capacitor also has a very low ESR, which aids its performance in those applications.
