Tantalum capacitors, often referred to as tantalum electrolytic capacitors, are a type of electrolytic capacitor made with a tantalum oxide dielectric and a tantalum metal helical anode. They are particularly well-suited for high-temperature, low-voltage and low-profile applications. Among all types of capacitors, tantalum capacitors are known for their high energy density, high reliability and very low ESR (equivalent series resistance).

The TWAE228K025CBSZ0000 is a tantalum capacitor from AVX Corporation, a leader in the production of passive electronic components including capacitors, resistors and inductors. Manufactured with a robust Pressure Contact (PC) termination, the capacitor is particularly suitable for high reliability and extreme temperature applications such as avionics, aerospace, and high temperature automotive components.

Its applications range from filtering and decoupling, to power supplies, signal filters, and oscillators. Unlike ceramic capacitors, tantalum capacitors can withstand higher temperatures and store more energy due to their higher capacitance per unit volume. They are also ideal where space is at a premium as they are small, lightweight and have very low ESR.

The TWAE228K025CBSZ0000 is a polarised capacitor, meaning it must be installed with the correct polarity to operate correctly. It features a 2.2µF capacitance and 25V DC rating. During operation, an oxide layer is formed on the anode and the nearly insulating anode-oxide-electrolyte layer acts as the dielectric layer of the capacitor.

The operation of the cutter charges and discharges the capacitor in a similar way to other types of electrolytic capacitors, depending on the applied voltage. During discharge, electrons exit the anode and are stored in the dielectric layer. During charging, the electrons flow from the cathode, through the electrolyte solution, to the anode.

In addition to their high performance, all AVX tantalum capacitors, including the TWAE228K025CBSZ0000, are RoHS compliant and meet the requirements of the European Union’s Restriction of Hazardous Substances Directive.

In conclusion, the TWAE228K025CBSZ0000 is a reliable, high-performance tantalum capacitor designed for demanding applications. The capacitor is suitable for low-voltage, low-profile and high-temperature applications, and provides a high capacitance per unit volume and low equivalent series resistance.
