Tantalum-Polymer capacitors are vital components in the electrical industry. They are mainly used for the filtering, decoupling, and storage of electrical energy. The T520B157M004ASE070 is a type of tantalum-polymer capacitor that has been designed for high performance in a variety of applications. This article will look at the application field and working principle of the T520B157M004ASE070.

This tantalum-polymer capacitor is a miniature, surface mount capacitor with a voltage rating of 16 VDC. It offers small size, high capacitance, and superior ESR performance at high frequencies. This makes it suitable for use in a wide range of applications, including portable electronic devices, mobile phones, power supplies, data converters, and automotive applications.

The T520B157M004ASE070 offers a variety of features. It has a low profile package that is just 20.7 mm high, which allows it to fit into confined spaces. The capacitor is also RoHS compliant and offers a wide operating temperature range of -55 °C to +85 °C. It is also highly reliable, with a proven mean time between failure (MTBF) of more than 100,000.

The T520B157M004ASE070 is a non-polarized capacitor, which means it can be wired into a circuit without regard for the direction of current flow. It also uses a non-toxic, polymer electrolyte that is highly resistant to corrosion and offers an exceptionally long service life.

The operating principle of a tantalum-polymer capacitor is based on the electrochemical reaction between the electrolyte and the tantalum material. This reaction creates a charge that is stored in the layers of the capacitor. The stored charge creates an electrical field that can be tapped to supply power when needed.

When the capacitor is disconnected from a power supply, the capacitor’s charge begins to leak off slowly, although it cannot generally be detected. However, this leakage reduces the capacitor\'s effective capacitance over time, which affects its performance. The capacitor can be recharged by connecting it to a power supply, which reverses the electrolytic reaction and restores the capacitor to its original performance.

In summary, the T520B157M004ASE070 is a high performance, miniature tantalum-polymer capacitor. It is designed for use in a range of applications, such as portable electronics, power supplies, and data converters. The capacitor is non-polarized and uses a non-toxic, polymer electrolyte that offers superior ESR performance at high frequencies. The operating principle of the capacitor is based on the electrochemical reaction between the electrolyte and the tantalum material, which creates an electrical field that can be tapped to provide power when needed.
