Tantalum - Polymer Capacitors

T540D337K004BH86057280 is a tantalum-polymer capacitor with a high power density and low ESR. The capacitor, which consists of two plated tantalum anodes, an electrolytic dielectric, and a conductive catholyte, is widely used in a variety of applications.

Application Field

T540D337K004BH86057280 capacitors are mostly used in high-temperature and high-pressure applications, such as pressure sensors and military-grade electronics. These capacitors are designed to meet the low-loss and high-temperature requirements of many industries, including aerospace, medical and telecommunications. They are also used for high-performance energy storage and for microprocessor timing and general-purpose filtering in power supply designs.

Working Principle

Tantalum-polymer capacitors are constructed with a tantalum pellet electrode and an electrolytic dielectric. A metallic anode is attached to the center of the pellet and an electrolyte is applied to the sides of the anode, forming a two-layer structure. When an electrical charge is applied, the anode plating must be large enough to prevent and dissipate the heat produced. An electrical field is formed, by which current flows through the electrolyte, increasing the capacitance.

The polymer material for the tantalum-polymer capacitor is a dielectric material that is added between the anodes. This material helps reduce the ESR, increases thermal stability, and improves the safety of the capacitor. It also helps provide higher capacitance in comparison to the standard tantalum construction.

The tantalum-polymer capacitor works through the same mechanism as a standard tantalum capacitor. When a voltage is applied, electrons flow through the capacitor in response to the electric field. This causes the capacitor to store electrical energy, creating an electric field around the wax. When the applied voltage is removed, the stored energy is discharged.
