Tantalum - Polymer Capacitors

T540B686K004DH87107280 is a high-performance tantalum - polymer capacitor (hereinafter referred to as capacitor). It is widely used in modern electronic circuits such as power management, automotive industry, industrial automation, telecommunication and medical equipment.

T540B686K004DH87107280 is composed of a tantalum core, an anode foil that is metallized to the tantalum core, a dielectric layer, a cathode foil and a polymer electrolyte. The metallized anode and cathode foil provides a higher capacitance density and improved electrical performance allowing for thinner and lighter designs.

The tantalum core provides higher temperature rating and mechanical strength; the circuit has a higher temperature rating than other capacitor technologies. This high temperature rating makes the capacitor well-suited for applications such as high-end notebooks and automotives.

This type of capacitor is mainly used in applications where high capacitance density and stable electrical performance are required. It provides the combined benefits of high capacitance, low impedance and a long cycle life over traditional aluminum electrolytic capacitors.

Application Field

T540B686K004DH87107280 is widely used in applications that require high capacitance density and stability such as power management, automotive industry, industrial automation, telecommunications and medical fields. It is suitable for a variety of applications including low frequency and switching power supply, Filtering and compensation, decoupling and CRC filtering.

Working Principle

The working of this capacitor is based on the principle of electrochemical deposition of metal (tantalum) onto an anode foil, which is then separated from the anode foil by a dielectric layer. A cathode foil is metallized to the tantalum core and the two metal foils are then connected with a polymer electrolyte.

When a voltage is applied across the capacitor, current flows between the metal foils, forming an electric field across the dielectric layer. This electric field creates an electrostatic charge that is stored in the metal foils. This stored charge is what forms the capacitor’s capacitance or energy storage ability.

The capacitance of the T540B686K004DH87107280 capacitor is dependent on the interelectrode distance, the amount of charge stored, the temperature and other parameters. The capacitor can withstand high temperature and has a long cycle life due to its physical construction.

Conclusion 

T540B686K004DH87107280 is an advanced tantalum - polymer capacitor. It offers a higher capacitance density and improved electrical performance over traditional capacitors. The capacitor is suitable for a variety of applications that require high capacitance, low impedance and long cycle life including power management, automotive, industrial automation, telecommunication and medical system. The working of the capacitor is based on the principle of electrochemical deposition of metal onto an anode foil, thus forming an electric field in the dielectric layer and storing charge in the metal foils.
