Tantalum - Polymer Capacitors

T541X158M003DH8705 is a type of tantalum - polymer capacitor which consists of two electrodes between which a polymer dielectric material is sandwiched. These capacitors offer high capacitance and high power dissipation in comparison with other similar capacitors due to their unique construction.

Application Field

T541X158M003DH8705 capacitors are mainly used in portable electronic devices such as mobile phones and PDAs, as well as in automotive and aerospace applications. They provide good capacitance and power for applications that require a significant amount of energy storage, such as those in portable consumer electronics. Additionally, the higher operating temperature range makes these capacitors suitable for automotive and aerospace applications.

Working Principle

Tantalum - polymer capacitors work by ionic conduction between the two electrodes. When a voltage is applied across the two electrodes, the dielectric material between them becomes polarized and creates a space charge that causes the positive ions to move towards the cathode and the negative ions to the anode. This movement of the ions establishes an electric field between the two electrodes, resulting in a capacitive effect that stores the electrical energy.

The capacitance of the device is determined by the space charge created in the dielectric material and the size of the electrodes. At higher temperatures, the dielectric material undergoes thermal expansion which increases the capacitance. This is an important feature of the tantalum - polymer capacitors as it allows them to have a wide operating temperature range.

Tantalum - polymer capacitors are also known for their high power density which is due to their low parasitic inductance and resistance. This low parasitic inductance and resistance also allow them to achieve high switching frequencies and speeds. This makes them ideal for high-speed data communication applications.

In addition, tantalum - polymer capacitors have excellent high temperature stability and long life cycle due to their unique construction. This feature makes them especially suitable for long life cycle applications that require high reliability.

Overall, T541X158M003DH8705 tantalum - polymer capacitors are ideal for applications that require high power, high capacitance and high temperature stability. They can be used in a wide range of applications from mobile phones and PDAs to automotive and aerospace applications.
