ALF20C681EH400

Aluminum electrolytic capacitors (AECs) are widely used in electronic components and equipment due to their low cost, high capacitance, and easy integration into circuits. The ALF20C681EH400 is a type of AEC designed to meet specific performance requirements. This capacitor model has a capacitance of 20uF, a voltage rating of 400V, and a maximum ripple current of 2.8A.

AECs work by storing electrical energy in the form of electric field and inversely proportional to the distance between two conducting surfaces. The capacitor is formed by using an anode (positively charged electrode) and a cathode (negatively charged electrode), which are separated by the electrolyte. AECs are ideal for power supply stabilization because they can rapidly charge and discharge, and their capacitance also remains relatively constant over wide temperature ranges.

The ALF20C681EH400 AEC is designed for applications that require high selectivity, stability, and reliability. It is suitable for a wide temperature range, with a maximum operating temperature up to 125°C, and a minimum temperature of -40°C. The capacitor also offers long life with a +105°C rated temperature, and up to 2000 hours at +85°C.

The ALF20C681EH400 is commonly used in AC/DC power converter circuits, DC/DC circuits, stabilizers, and inverters. It is also used in audio-frequency amplifiers, switching power supplies, and other high-power electronic equipment. The capacitor has a low impedance, making it ideal for high frequency response applications. It is also designed for high vibration and shock conditions, and is resistant to high humidity, making it suitable for use in harsh environments.

In terms of design, the ALF20C681EH400 features compliant snap-in leads for secure and easy mounting, a low-profile design for space-efficient installation, and a snap-on plastic skirt for added insulation. The capacitor has passing ratings for safety standards such as UL, VDE, and ABNT, making it suitable for international markets where safety and reliability are highly important.

Overall, the ALF20C681EH400 aluminum electrolytic capacitor is an ideal choice for a wide range of high power applications. Its high temperature and humidity resistance, along with its long life and reliable performance, make it a reliable solution for power management projects.
