25YK22MEFCTA5X11

Aluminum electrolytic capacitors are widely used in a variety of applications, from power supplies and general purpose circuits to specialty applications in communications and transportation systems. The particular product in question is the 25YK22MEFCTA5X11 capacitor. This product utilizes an organic electrolyte and is designed mainly to be used in switch mode power supplies and displays.

The capacitance specification of this product is 22μF (nominal capacitance) at a rated voltage of 25V. It is also labeled as having a ripple current rating of 1.5A RMS. This electrical rating corresponds to a steady-state pulsating current typically seen in switching power supplies. The capacitor’s ESR (equivalent series resistance) is 2.5Ω max and its ESL (equivalent series inductance) is 4nH max, both at 125kHz, 0.2Vrms.

In order to get maximum performance, the 25YK22MEFCTA5X11 capacitor must be used within its specified operating temperature range of -40 to +85°C. This product exhibits a high self-healing property, which results in improved reliability and long life. The product is also available with RoHS compliant terminations. The product is UL certified (for USA and Canada), CSA certified (for Canada) and VDE certified (for Europe).

The working principle of the 25YK22MEFCTA5X11 aluminum electrolytic capacitor is based on a chemical system in which a film of oxide is formed on two layers of aluminum foil. The two layers are separated by a paper spacer and wound together into a can type package. The electrolyte in the can is an electrolyte liquid or electrolyte gel. The electrolyte solution assists in increasing the formation of the oxide layer on the aluminum surfaces, thus increasing the surface area of the electrodes, which in turn increases the capacitance of the formed capacitor. In addition, the electrolyte assists in preventing oxidation of the aluminum surfaces.

The electrolytic capacitor will always attempt to maintain equal voltage on both sides of the capacitor. This is done with current flowing through the capacitor in the reverse direction of the external power. Once the equilibrium between the two sides of the capacitor is established, no current will flow through the capacitor. This capacitor also exhibits a large amount of voltage droop under load, meaning the voltage on the capacitors increases as it is charged.

From the above description of the 25YK22MEFCTA5X11 aluminum electrolytic capacitor, it is clear that this product is designed mainly to be used in switch mode power supplies and displays. This capacitor provides excellent electrical characteristics such as a low impedance, high ripple current rating, and high capacitance. The product is also available with RoHS compliant terminations, making it suitable for applications that require adherence to environmental regulations. Additionally, the product is UL, CSA, and VDE certified, so it can be used in a variety of applications with confidence.
