Introduction to Aluminum Electrolytic CapacitorsAluminum electrolytic capacitors are widely used due to their large capacitance, good reliability and long service life. They are typically used in electronic circuits to filter out voltage fluctuations, help deaden transients in the circuit, help shape pulse signals and increase the current that a circuit can handle. They are available in various sizes, voltage ratings and capacitance values.The MAL202133471E3The MAL202133471E3 is an aluminum electrolytic capacitor that features a radial leaded aluminium case. This capacitor is rated at 1300 volts and has a capacitance value of 47 µF. It is suitable for high voltage and high frequency applications, including motor drives, frequency converters and switch mode power supply systems. It is also well suited to applications involving surge current such as starter motors, door openers and welders.Principle of OperationThe basic idea behind an aluminum electrolytic capacitor relies on two aluminum foils being separated by an electrolytic paper soaked in an electrolyte solution. This solution acts as an insulator and allows voltage to remain steady across the capacitance.A perfluorosulfonic acid-based electrolyte solution is used which is thin, non-flammable and does not freeze or evaporate over long periods. This allows for a low series resistance and a wide frequency range. Aluminum electrolytic capacitors are robust and highly resistant to temperature, vibration and mechanical shock.Applications of the MAL202133471E3The MAL202133471E3 is ideal for applications where high current and/or high voltage are needed. It is commonly used in motor drives and frequency converters, as well as in switch mode power supply systems. It is also suitable for surge current applications, such as starter motors, door openers and welders.This capacitor is particularly suitable for automotive and industrial applications, due to its robust construction, high performance, and stable operation. Other common applications include energy storage and filtering, audio crossover networks, and PFC circuits.ConclusionThe MAL202133471E3 is an aluminum electrolytic capacitor that offers high current and/or high voltage operation in a wide range of applications. This capacitor relies on a perfluorosulfonic acid based electrolyte solution for its low series resistance and wide frequency range, making it suitable for automotive and industrial applications. It is commonly used in motor drives, frequency converters, switch mode power supply systems, energy storage and filtering, audio crossover networks, and surge current applications such as starter motors and door openers.
