Tantalum - Polymer Capacitors

Tantalum - polymer capacitors are made from two components and provide a reliable and robust electrolytic capacitor solution.

T543D477K006AHW0257505 capacitors have been developed based on the conventional design of tantalum capacitors. This type of capacitor has been designed to provide a low impedance solution and it features low equivalent series resistance (ESR), high temperature and voltage ratings, low temperature coefficient and fast charging/discharging characteristics.

The capacitance of these capacitors is a function of the area of the anode and cathode, as well as the dielectric permittivity. A dielectric consists of layers of tantalum and polymer, providing an ideal combination of electrical, physical, and chemical properties.

Tantalum-polymer capacitors are often referred to as "ultra-low ESR" capacitors due to the reduced equivalent series resistance that is achieved through the use of this type of design. The reduced ESR allows for better heat dissipation, lower ripple current, higher ripple current capability and better high-frequency performance.

T543D477K006AHW0257505 capacitors have the highest voltage and temperature ratings available in the market and they feature enhanced load and surge characteristics. They can work in extremely humid and electrical noise environments, making them ideal for high-power LED lighting applications in automotive, industrial and commercial settings.

Tantalum-polymer capacitors offer a longer service life, higher levels of reliability, and improved performance at higher temperatures, when compared to other types of electrolytic capacitors. They are also more resistant to voltage surges, which makes them suitable for use in power supply circuits, automotive, and other high-voltage applications.

Tantalum-polymer capacitors are excellent for use in locations where space and temperature requirements dictate the use of a smaller device and a device that can withstand extreme temperatures. These capacitors are typically used in laptop computers, smartphones, and automotive, industrial, and military applications. They are also well suited for low voltage applications such as in mobile phones and tablet computers.

The working principle of T543D477K006AHW0257505 capacitors is by use of a polarized dielectric system. The dielectric consists of a fixed and a mobile layer of tantalum and polymer film. When a potential is applied across the capacitor, the mobile layer of tantalum and polymer film quickly swells and forms a layer of electrochemical bonds.

The conductive layer of the polymer accumulates charges on each side, resulting in a capacitance. This capacitance will remain constant over a wide temperature range, making these types of capacitors ideal for high temperature applications. The principle of operation makes the capacitor resistant to temperature, moisture, shock and vibration.

Tantalum-polymer capacitors offer cost-efficient alternatives for many applications. They provide advantages over other capacitor types such as aluminum electrolytic or mineral oil filled capacitor designs with respect to size, temperature coefficient and reliability. The low impedance, high capacitance and low ESR characteristics of tantalum-polymer capacitors make them suitable for use in a wide range of applications.
