Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, abbreviated as AI-E caps, are powerful components used in many electrical circuits. They are often used in DC power supply filtering, frequency separation, resonance, smoothing, timing, and other analog application fields. The MAL201350339E3 capacitor, in particular, is often used for consumer and industrial applications due to its versatility and wide range of features.

Construction

AI-E capacitors are constructed of an anode and cathode, enveloped by two aluminum foil layers and a dielectric separator. All of these elements are carefully layered within a cylindrical can. The capacitor’s anode is typically constructed of pure aluminum that’s etched with a pattern of hemispherical pores. This porous and textured anode allows electrolyte to permeate the entire part, acting as an ionically conductive bridge between the anode and cathode.The entire capacitor also needs to be saturated in an electrolyte solution in order to complete its operation. As voltage is applied to the pins, the electrolyte solution will become ionized, allowing positive and negative charges to accumulate on the anode and cathode respectively. These charges are then what creates the capacitor’s overall capacitance.

Performance Characteristics

The performance characteristics of AI-E caps are determined by a variety of factors. For example, the anode’s area and its etching design will have an impact on the part’s capacitance. Additionally, the capacitor’s size, working voltage, temperature behavior, and endurance also need to be taken into consideration. The MAL201350339E3, in particular, is a general purpose capacitor used for consumer and industrial applications alike. It has a 25V voltage rating, comes in a 70mm x 25mm size, and features a solid aluminum body. At 25°C, this capacitor offers a 5uF capacitance with a maximum 45,000 hours life expectancy. It also has a ±20% allowable capacitance drift over its specified temperature range.

Working Principle

AI-E capacitors operate on the principles of electrochemistry and electrolyte ionization. When voltage is applied to the pins, the electrolyte solution becomes ionized, allowing positive and negative charges to accumulate on the anode and cathode respectively. The anode is then able to draw the extra electrons produced by the electrolyte, allowing it to become increasingly negatively charged. The opposite holds true for the cathode which gains additional protons, allowing it to become increasingly positively charged. This creates a potential difference between the two ends of the capacitor. When a current is applied to the capacitor, the positive charges on the cathode are attracted to the negative charges on the anode, allowing current to flow across the two points. The capacitor then uses this current flow to store and output energy.

Conclusion

The MAL201350339E3 is a powerful and versatile aluminum electrolytic capacitor designed for consumer and industrial application fields. It boasts a 25V voltage rating and solid aluminum body, and features a 5uF capacitance at 25°C. With a 45,000 hours life expectancy and a ±20% capacitance drift, the MAL201350339E3 is a great choice for those looking to filter DC power, separate frequencies, smooth out signals, or any other applications requiring high-quality capacitance. Ultimately, the MAL201350339E3 is just one example of the many aluminum electrolytic capacitors used in the world today. AI-E caps are powerful components that offer a variety of features and performance characteristics, making them ideal for many different types of applications.
