Tantalum - Polymer Capacitors

Tantalum polymer capacitors are a type of capacitor constructed using a tantalum metal case with an electrolyte filling of solid polymer dielectric. They offer a number of benefits compared to traditional electrolytic capacitors, such as higher reliability, higher ripple current, narrower tolerance range, and lower impedance. They are suitable for a wide range of electronic applications, from high frequency interference suppression to capacitive touch sensing.

T540D227M006BH85057280 Application Field and Working Principle

T540D227M006BH85057280 is a type of tantalum - polymer capacitor, also known as a Chip tantalum - Polymer capacitor. It has a small size and large capacitance, and is designed for capacitive load applications in low and high impedance power supplies. It is suitable for use in high frequency circuit, filtering, and decoupling applications.

This type of capacitor has a two-segment, solid aluminum core electrode, with one segment of the aluminum outside the dielectric material, and the other within it. This design helps create a low-inductance capacitor that is capable of managing large high frequency currents. The core is also designed to be able to withstand large temperature changes, enabling reliable operation in extreme temperatures.

The working principle of this capacitor is based on the principle of charge storage. When electrical voltage is applied, an electric field is created between the electrodes of the capacitor, which causes a redistribution of charges across the electrodes and electrostatic layers. This causes a change in capacitance and permits an exchange of energy between the terminals.

In addition, the capacitance of the capacitor is dependent on the height of the electrostatic layers and the area of the electrodes. The thickness of the dielectric layers can be controlled to adjust the capacitance, making them ideal for applications in which the capacitance must be precisely adjusted.

The T540D227M006BH85057280 can be used in a broad range of applications, such as power supplies, short circuits, high frequency filter circuits, decoupling, and low and high impedance filter circuits. Its increased operating temperature range makes it suitable for use in harsh environments.
