Its application scope also covers notebook computers and other miniature digital products, mobile phones, as well as home theater and car audio equipment.

Working principle of 226TTA450M

The basic structure of 226TTA450M aluminum electrolytic capacitor is composed of aluminum foil anode, electrolyte-soaked paper, conductive adhesive and an aluminum oxide film. The electrolyte is soaked in a paper with a small thickness of synthetic fiber paper as the dielectric material. The aluminum foil is covered with anodized aluminum oxide film. As the voltage applied to the capacitor increases, the electric field in the aluminum oxide film increases and the leakage current increases. The 226TTA450M aluminum electrolytic capacitor has an advantage over other electrolytic capacitors in that it has high ripple current capability, making it ideal for applications such as power supplies, converters, and other high-frequency switching circuits.

When voltage is applied, the ions of the dissolved electrolyte are driven to the surface of the aluminum oxide film, forming an insulating layer. This layer is also known as \'statical behavior of the electrolyte\'. The thickness of the oxide layer is proportional to the applied voltage, so that the higher the voltage applied to the capacitor, the thicker the oxide layer, which consequently increases the capacitance. The contact between the solid and liquid electrolyte reduces the leakage current. Additionally, a conductive adhesive is used to create contact between the aluminum oxide film and the aluminum foil, thus forming the 226TTA450M aluminum electrolytic capacitor.

The 226TTA450M aluminum electrolytic capacitor is a common application in power converters, as its larger capacity allows it to store large amounts of energy, thus increasing the efficiency of the overall power converter circuit. Additionally, due to its high leakage current capability, the 226TTA450M aluminum electrolytic capacitor is also suitable for use in high-frequency circuits and various filtering applications. In conclusion, the 226TTA450M aluminum electrolytic capacitor is an important component in various power conditioning and switching circuits, due to its superior performance and large capacity.
