These capacitors are used in power supplies, audio amplifiers, and other applications to store electrical energy and to provide filtering or voltage regulation. The AFK477M25G24T-F aluminum electrolytic capacitor is a high quality device with an extended lifetime, featuring increased reliability and efficiency compared to older models.

Construction and Specifications

The AFK477M25G24T-F is an aluminum electrolytic capacitor constructed with an aluminum oxide dielectric and robust sealing construction. The product is rated for a 105°C temperature range with a maximum operating voltage of 25 volts and a capacitance of 477 microfarads. The capacitor is typically sized in a 25 x 23mm case with a height of 10mm.The capacitor is characterized by a low ESR (equivalent series resistance) and high ripple current of up to 14.2A, with a maximum operating temperature of + 105°C for long life operation. The rated capacitance tolerance is ±20%, and the lifetime is 5000 hours at 20°C and 1000 hours at 70°C. The capacitor is RoHS compliant, marking it as free of lead and other harmful materials.

Application Field and Working Principle

The AFK477M25G24T-F aluminum electrolytic capacitor is well-suited for applications in both consumer and industrial electronics. It is commonly used in power supplies and audio amplifiers, and in voltage regulation systems, as it has a high capacitance value and can handle a large amount of current. The capacitor is robust and reliable, making it suitable for use in a variety of harsh environments.The capacitor works by storing electrical energy within an insulating dielectric material. When a voltage is applied to the capacitor\'s terminals, electric fields create a Faraday shield, blocking current flow and storing electric charge. This charge can then be released or regulated as needed, providing voltage regulation or power supply filtering.

Conclusion

The AFK477M25G24T-F aluminum electrolytic capacitor is an efficient, robust product designed for use in harsh environments. With a long lifetime and high capacitance, the capacitor is ideal for voltage regulation and power supply filtration applications. It is also RoHS compliant, indicating that it is free of lead and other hazardous materials.
