Tantalum capacitors are electrochemical capacitors that use a tantalum anode or cathode with an electrolyte forming dielectric single layer capacitors and double layer capacitors. The T86C475M035ESAS capacitor is a representative SEACap/Conductive solid electrolytic capacitor from TDK products, which is suitable for high current applications. As a kind of tantalum capacitor, it not only has high electrochemical properties, low ESR and low voltage dropout, but also has excellent non-inductive characteristics. When it comes to the application field and working principle of the T86C475M035ESAS, it is worth noting.

Application Field of the T86C475M035ESAS

The T86C475M035ESAS is a high current and wide temperature range product from TDK SEACap series with a capacitance of 4.7µF and an ESR of 0.05Ω±20%. This product has an operating temperature range of -55℃ to 125℃, it features a low impedance, high ripple current, long life, and non-inductive characteristics. The product structure is small, with a diameter of 8.0mm and a height of 6.2mm, making it suitable for use in the power supply or motor drive part of various small portable devices. The product is also widely used in home appliances, automotive electronic control systems, and other fields that require high vibration capability and high ripple current.

Working Principle of the T86C475M035ESAS

The T86C475M035ESAS is a kind of leadless tantalum capacitor with a conductive solid electrolyte, which features high capacity in a small size. The capacitor has two terminations, one of which is the anode and the other is the cathode. The anode is made of sintered tantalum manufactured using a patented electroless plating process while the cathode is made of conductive particles, usually manganese dioxide. The anode and cathode are separated by a conductive solid electrolyte, which is formed by using polymeric materials as a medium. The polarized electrolyte is formed after a full anodic-plating process at the interfaces of the anode and the electrolyte, and the conductivity between them is enhanced by the high-speed impregnation of the electrolyte.

When the capacitor is connected to power, current will flow from the anode to the cathode that produces a voltage difference in the two interfaces. This voltage difference creates an electric field that stores the energy in the capacitor. As the current flowing through the capacitor increases, the voltage stored in the capacitor will be compressed, that’s why the product has a specified maximum voltage limit. Under normal circumstances, the capacitor can provide a stable output, and the output current will not drop in the long run, owing to the excellent electrical conductivity and low ESR characteristics of the manganese dioxide cathode material used.

Conclusion

In summary, the T86C475M035ESAS is a high-current and wide-temperature-range product from TDK SEACap series. It features a low impedance, high ripple current, long life, and excellent non-inductive characteristics. The product is suitable for use in the power supply or motor drive part of various small portable device, home appliances, and automobile electronic control systems. The capacitor has two terminations, one of which is the anode and the other is the cathode, which are separated by the conductive solid electrolyte. When the capacitor is connected to power, current will flow from the anode to the cathode that produces a voltage difference in the two interfaces, resulting in an electric field that stores the energy in the capacitor.
