Tantalum - Polymer Capacitors: T520W107M010ATE040 Application Field and Working Principle

Tantalum-polymer capacitors are a type of electrolytic capacitor that offer the advantages of both polymer and electrolytic technology. They are a relatively new type of capacitor, combining the strength and reliability of tantalum capacitors with the flexibility and lower cost of polymer capacitors. Designed for use in demanding automotive, medical, and industrial applications, they are particularly suited to applications where small form factor and high capacitance are required. The T520W107M010ATE040 is a tantalum-polymer capacitor manufactured by AVX Corporation, and in this article we will take a look at its application field, and its working principle.

Application Field

Typical applications for the T520W107M010ATE040 include automotive electronic systems, medical electronic devices, portable electronic products and other applications where superior performance and low impedance are required. The T520W107M010ATE040 has an impressive 12.5mm diameter case with a short profile of 5.6mm, providing a large amount of capacitance in a small case size, making it perfect for use in applications where space is at a premium. The robust construction and design makes it suitable for operation in extreme temperatures, high-vibration environments, and in constant humidity conditions.

Working Principle

Tantalum capacitors are primarily made up of two electrodes, one of which is made of tantalum and the other of a conductive material, typically a porous carbon-containing material or a metallic grid. The tantalum electrode is covered with a liquid electrolyte. During operation, electric current passes through the capacitor, causing charges to accumulate on the two electrodes. This then creates an electric field between the two electrodes, resulting in the capacitor being charged.The electrical properties of the T520W107M010ATE040 are significantly different from conventional electrolytic capacitors. It has an electrolyte layer that is about 5 times thinner than a traditional tantalum capacitor and the electrolyte is made from a polymer film, creating a more stable device. This improves the voltage rating of the device and increases the ripple current capacity.The capacitance of the T520W107M010ATE040 ranges from 22μF to 330μF and its rated temperature range is from -55°C to 125°C with a rated voltage of 6.3V - 10V. The device features a low ESL and low ESR, making it well suited for high ripple current applications and generating an extremely small amount of heat.

Conclusion

The T520W107M010ATE040 is an ideal capacitor for demanding automotive, medical and industrial applications where small form factor and high capacitance are required. Its polymer electrolyte construction and robust design makes it suitable for use in extreme temperatures and highly humid environments. Its high capacitance and rated temperature range, coupled with its low ESL and ESR make it suitable for high ripple current applications.
