Tantalum-polymer capacitors are a new type of capacitor, combining the high reliability of tantalum capacitors with the high capacitance and small size of polymer capacitors. This article will focus on the application field and working principle of the T55A336M2R5C0180 capacitor.

Application field of the T55A336M2R5C0180 capacitor

The T55A336M2R5C0180 is a Grade A, AEC-Q200 qualified, attractive alternative to aluminum electrolytic capacitors in many applications. It is a general-purpose 5.5V capacitor with an ultra-low ESR and small size. The product features a capacitance of 330 μF and a resonant frequency of 4.7MHz.

Tantalum-polymer capacitors are great for many applications such as audio applications, voltage regulator circuits, and DC-DC converter circuits. they can also be used in automotive systems, where they are often favored due to their smaller size and superior performance. Additionally, they are increasingly used in portable and medical electronics as tantalum capacitors offer superior temperature stability and long-term reliability over other types.

Working principle of the T55A336M2R5C0180 capacitor

Tantalum-polymer capacitors work similarly to aluminum electrolytic capacitors. They are constructed with an anode, a cathode, and a separator. The anode and the separator are both porous and filled with a liquid electrolyte, while the cathode is constructed from a polymer material. The anode, cathode, and separator are sealed within a package and filled with the electrolyte.

When the capacitor is powered up, an electric current passes through the anode, causing an electrochemical reaction that forms a thin layer of tantalum oxide on the anode\'s surface. This layer acts as an insulator, preventing further reactions and current flow. As a result, charge is stored within the capacitor and will remain until the voltage is removed.

Tantalum-polymer capacitors have several benefits over other types of capacitors due to their construction. These capacitors boast a wide range of capacitances, low equivalent series resistance (ESR), and high temperature operation. The ESR and capacitance of these capacitors remain stable over a wide operating temperature range, making them suitable for use in high-temperature applications.

Conclusion

The T55A336M2R5C0180 is a tantalum-polymer capacitor that can be used in a variety of applications. These capacitors offer a wide range of capacitances, low ESR, and high-temperature operation, making them an attractive option for many applications. The working principle of these capacitors is similar to that of aluminum electrolytic capacitors, but with a layer of tantalum oxide providing insulation and charge storage.
