What is a Tantalum-Polymer Capacitor?

A tantalum-polymer capacitor is one of the most advanced technology used in the electronic industry today. They are used in many applications such as power supplies, audio electronics, and automotive systems. This type of capacitor contains an electrolyte material between two conductive plates and a dielectric material between the plates. As a result, it has the ability to store an electric charge and is more reliable than the conventional aluminum electrolytic capacitors. These capacitors have a significantly longer life span and can withstand extreme temperatures, making them ideal for many different applications.

T543X226M063AHE0757280 Application Field and Working Principle

The T543X226M063AHE0757280 is a tantalum-polymer capacitor from the X2 series. It is a non-solid version capacitor with dimensions of 7.0 x 5.7 x 2.3 mm, a rated temperature of +85°C, and a rated voltage of 16V. It has a maximum capacitance of 220 µF and a tolerance of 10%. This series has been designed to meet the requirements of high temperature, hostile environments and is used in applications such as Automotive, Computer and Industrial Control, Aerospace, and High Voltage Power Supplies.The main principle of operation behind a tantalum-polymer capacitor is based on the electrochemical properties of the conductive plates that are in contact with the electrolytic material. This material consists of saline solutions of different metals like manganese, phosphorous, and zinc. When a voltage is applied to the plates, the electrolyte material does not increase in volume but instead the charge is stored on the surface of the plates. Consequently, this allows for a much higher capacitance than that of traditional aluminum electrolytic capacitors.

Advantages of Tantalum-Polymer Capacitors

Tantalum-polymer capacitors are one of the most advanced capacitors available today. They offer several advantages compared to other capacitor types:• High Reliability: These capacitors have a high-quality construction and therefore offer a high reliability even in extreme temperatures and other harsh environments.• High Capacitance: The voltage drop across the plates causes the electrolyte material to be charged and stored, which makes it possible to achieve higher capacitances than those of aluminium electrolytic capacitors.• Low-ESL: All capacitors have an Equivalent Series Inductance (ESL) and the lower the ESL the better the performance. Tantalum-polymer capacitors offer significantly lower ESL than that of aluminum electrolytic capacitors, making them more suitable for higher frequencies.• Low-ESR: Equivalent Series Resistance (ESR) or current-leakage is a measure of how much current a capacitor can handle. The lower the ESR, the better the performance. Tantalum-polymer capacitors offer significantly lower ESR than that of aluminum electrolytic capacitors.• Long Life Span: These capacitors can withstand high temperatures and are more reliable than their aluminum electrolytic counterparts. Consequently, they offer a longer life span and require fewer changes.

Conclusion

Tantalum-polymer capacitors are widely used in applications such as power supplies, audio electronics, and automotive systems due to their high reliability, long life span, and low ESR, ESL characteristic. The T543X226M063AHE0757280 is an example of a tantalum-polymer capacitor that offers these advantages and is suitable for high temperature and hostile environments.
