Introduction to Tantalum - Polymer Capacitor

Tantalum - Polymer Capacitors (Ta-P) is one of the most popular solutions for many electronic applications. This type of capacitor has very low ESR, long lifecycle, and it’s stable operation. It’s also an alternative solution to tantalum electrolytic capacitors. Ta-P capacitors have different styles, shapes and packages, allowing them to be adapted to many applications, from consumer to industrial products. This type of capacitor is gradually replacing aluminum electrolytic capacitors in many circuits and applications.

The Different Types of Ta-P Capacitors

There are three main types of Ta-P capacitors according to construction: Single-Layer Ta-P Capacitors, Double-Layer Ta-P Capacitors, and Multi-Layer Ta-P Capacitors. Single-Layer Ta-P Capacitors are constructed using a mix of an electronically conductive polymer as dielectric in a “tantalum container”. A single anode made of solid titanium dioxide and a low-ohmic carrier layer of conductive polymer covers the anode layer. Compared to electrolytic capacitors, Single-Layer Ta-P Capacitors offers a higher reliability and long life. Double-Layer Ta-P Capacitors are constructed with a tantalum anode, an electrolyte solution composed of conductive polymer as well as a liquid electrolyte, and a cathode made of two layers of titanium dioxide. This type of capacitor has a higher capacitance than single-layer capacitors and is ideal for high-voltage applications. Double-layer Ta-P Capacitors also offer excellent ripple current rating and ESR curve control.Multi-Layer Ta-P Capacitors are constructed with multiple layers of tantalum, an electrolyte solution composed of conductive polymer as well as a liquid electrolyte, and a cathode made of titanium dioxide. This type of capacitor has a higher capacitance than single-layer and double-layer capacitors, providing a better ripple current rating and ESR curve control.

The T598D227M006ATE0257280 Application Field and Working Principle

The T598D227M006ATE0257280 Ta-P Capacitor is designed to meet the needs of LED backlighting applications. It is a Single-Layer Ta-P Capacitor with a tantalum anode and a titanium dioxide cathode. It has an operating voltage of 6,3V and a capacitance of 2,7µF. Its low ESR makes it suitable for applications requiring fast and accurate response times.The working principle of the T598D227M006ATE0257280 relies on the use of conductive polymers between the layers of the capacitor, creating a low resistance path for the flow of electricity. The conductive polymers can withstand high temperatures and provide a stable electrical path. When the capacitor is energized, the positive charges accumulate on the anode, while the negative charges accumulate on the cathode, thus creating an electrical field across the capacitor. The electric field enables an electric current to flow through the capacitor.

Conclusion

Tantalum - Polymer Capacitors (Ta-P) are becoming increasingly popular in many electronic applications. They come in different styles, shapes and packages, making them suitable for all sorts of circuits and applications. The working principle of Ta-P capacitors relies on the use of conductive polymers between the layers of the capacitor, creating a low resistance path for the flow of electricity. The T598D227M006ATE0257280 Ta-P Capacitor is especially designed for LED backlighting applications with a high capacitance and low ESR, resulting in fast and accurate response times.
