T540D477M003CH87057280 belong to a variety of capacitors known as Tantalum – Polymer capacitors. This type of capacitors is used in many electronic applications that require efficient power control and energy storage.

Compared to other types of capacitors, the Tantalum – Polymer type provides several advantages such as larger capacitance values in the same size package, lower ESR values, low profile and low inductance. Specifically, the T540D477M003CH87057280 capacitor offers a capacitance of 470 uF, working voltage of 6.3V and an ESR of 18mΩ.

The application fields for Tantalum – Polymer capacitors are wide, ranging from high-end consumer electronics, to automotive and military products. In consumer electronics, these capacitors are used to smooth peak currents and decoupling power supply lines to maintain a steady voltage to the load.

On automotive applications, these capacitors are used to dampen perturbations produced by the motor during acceleration. In military applications, they are used to guarantee reliable operation while withstanding extreme environmental conditions.

The working principle of a Tantalum – Polymer capacitor is the same than any other polarized capacitor: two electrodes of different materials are separated by a thin dielectric. The polarized capacity of the device is obtained when applying an electric charge to one of the terminals.

However, the Tantalum – Polymer capacitor is special as many dielectric layers are interspersed between the two electrodes. This gives the device a much better capacitance-voltage ratio than other types of capacitors. Additionally, these capacitors are very small in size and do not suffer from significant changes in their capacitance due to temperature variations.

Tantalum – Polymer capacitors are ideal for applications where efficient energy storage and power control are necessary. The combination of small size, low ESR and large capacitance makes them suitable for a wide range of applications. Moreover, their working principle allows them to withstand extreme environmental conditions, making them also suitable for military products.
