Working Principle

Tantalum-polymer capacitors consist of a tantalum anode surface coated with a polymer dielectric material. The dielectric film is made up of several dielectric layers which are produced by vacuum deposition techniques. The anode is usually made of nickel, stainless steel, or molybdenum. As voltage is applied to the device, an electric field is generated across the dielectric interface, generating a current flow and charging the capacitor. When the voltage reaches its peak, the capacitor reaches its maximum capacitance. The current then decreases, and the capacitor discharges. The electrical field across the dielectric interface and the current are both proportional to the applied voltage.

The unique property of Tantalum-polymer capacitors is their high dielectric constant, which is much greater than conventional aluminum, electrolytic, or ceramic capacitors. This results in a higher charge storage capacity, which makes the capacitor suitable for high-power applications. The polymer film is also highly temperature-stable, and the capacitance remains more stable over a wide range of temperatures, making it ideal for high-temperature environments. The T540D157M006BH86057280 is highly resistant to vibration, making it perfect for aerospace, automotive, and industrial applications.
