Introduction to Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, commonly known as aluminum electrolytic caps or aluminium electrolytic caps, are widely used in many electrical and electronic equipment. As a kind of electrochemical capacitors, aluminum electrolytic capacitors have excellent electrical characteristics, including high capacitance in a very small volum, low leakage current, low ESR (Equivalent Series Resistance), and high ripple current. The function of aluminum electrolytic capacitors is mainly as a storage device. It can store energy in the form of a charge and then release it quickly when needed to protect the electrical components from damage due to overcurrent.

UKW1H472MRD Application Field and Working Principle

UKW1H472MRD is a type of aluminum electrolytic capacitors developed by United Chip Technologies. This capacitor is a miniaturized surface mount product that is designed for high density boards and offers superior performance and reliability. UKW1H472MRD is mainly used in mobile phone baseband, Wi-Fi modules, RF amplifiers, digital photo frames and other fields. Its working principle is based on Faraday\'s Law which states that the amount of electric charge stored on a capacitor is directly proportional to the voltage applied to the capacitor. In other words, the higher the voltage applied to the capacitor, the more electric charge the capacitor can store. The stored electric charge can then be released quickly when needed. The UKW1H472MRD aluminum electrolytic capacitor produces an alternating current when voltage is applied to it. It consists of a rolled aluminium foil anode and cathode which are separated by a dielectric layer of paper impregnated with an electrolyte. The capacitor can store much more electric charge than non-electrolytic capacitors in a very small volume. The UKW1H472MRD aluminum electrolytic capacitor has a rated operating temperature range of -55 to +125 Celsius, a working voltage of 16VDC, a rated capacitance of 47μF, a leakage current of 0.5 CV or 5μA, whichever is greater, and a maximum ESR of 0.3 Ohms. This capacitor provides an excellent combination of high capacitance, low ESR, and high ripple current and is ideal for use in high performance digital circuits.

Conclusion

In conclusion, aluminum electrolytic capacitors are widely used in many electrical and electronic devices due to their superior electrical characteristics. UKW1H472MRD is a type of aluminum electrolytic capacitor developed by United Chip Technologies that is used mainly in mobile phone baseband, Wi-Fi modules, RF amplifiers, digital photo frames and other fields. The UKW1H472MRD produces an alternating current when voltage is applied and it is rated to store a small amount of electric charge and may be used to protect electrical components from damage due to overcurrent.
