Introduction to Tantalum - Polymer Capacitors

Tantalum-polymer capacitors are one of the most commonly used types of capacitors, offering a reliable and longer lasting energy storage solution. These capacitors are constructed out of a two-film sandwich that consists of a tantalum anode (positive material) and a polymer cathode (negative material).

T540D687K003AH86057280 Application Field and Working Principle

The T540D687K003AH86057280 capacitor is a surface-mount tantalum-polymer capacitor with a capacitance value of 68 μF and a voltage rating of 6.3V. This capacitor is often used in power management applications, as it can provide stable DC electricity for a wide range of devices. It is also commonly used for decoupling and smoothing of power supplies and voltage boundaries.

Tantalum-polymer capacitors work on the principle of dielectric absorption. This involves the use of two films, with one acting as the anode and the other acting as the cathode. As the voltage across the terminals is increased, the dielectric material of the anode is attracted to the cathode and absorbs energy, allowing the capacitor to store charge. When the voltage across the terminals is reduced, the dielectric material releases its stored energy, allowing the capacitor to discharge.

Benefits of Tantalum-Polymer Capacitors

The T540D687K003AH86057280 provides several advantages over traditional capacitors, including a longer life span, a greater capacitance value for a smaller size, a higher temperature coefficient, and a higher maximum operating temperature (125°C). Additionally, it is relatively inexpensive, making it a desirable choice for many power management systems.

Tantalum-polymer capacitors are well-suited for use in a variety of applications, from cellular phones to aerospace applications. They are often used as an alternative to ceramic capacitors, as they offer higher capacitance values and a larger temperature coefficient range.
