Aluminum Electrolytic Capacitors

Mal213691185E3 is a type of aluminum electrolytic capacitor, one of the most widely used components in electrical and electronics applications. This type of capacitor is an aqueous electrochemical device, where the anode is typically made of aluminum foil and the cathode consists of a conductive metal oxide. This combination of materials creates an electrolyte solution between the anode and the cathode, which gives the capacitor its main benefit; the ability to store electrical energy.

Application Field of MAL213691185E3

MAL213691185E3 is suitable for a wide range of electrical applications, from signal filtering to power conditioning. In signal-filtering applications, the capacitor is often used to reduce noise in AC signals. Electrolytic capacitors are also commonly used in power conditioning, allowing for the smoothing of DC power output from voltage regulators, transformers, and other linear power sources. The capacitor’s high operating voltage and capacitance also make it useful for providing surge protection for high voltage circuits.

Working Principle of MAL213691185E3

The working principle behind MAL213691185E3 is based on Faraday’s Law of Electromagnetic Induction. When voltage is applied across the capacitor, current is generated through epoxide bonded aluminum (EBA) foil. The ions in the electrolyte are attracted toward the cathode, forming a double layer around it. This double layer is what makes the capacitor an effective storage device. As charge accumulates in the double layer, the applied voltage is divided into two parts; one part pushing electrons into the double layer, and the other part controlling the diffusion of ions in the electrolyte.

This basic operation only works within the capacitors’ designed operating voltage range. As the applied voltage is increased, the capacitance decreases until it reaches a minimum, a phenomenon known as voltage collapse. Conversely, when the applied voltage is decreased, the capacitance increases until it reaches a maximum, a phenomenon known as voltage recovery.

Conclusion

MAL213691185E3 are widely used in many electrical and electronics applications as it can store and distribute electric charge within a stable range. Its applications in signal filtering, power conditioning, and surge protection are just part of the electrochemical device’s many useful capabilities. With its high capacitance and stable voltage range, MAL213691185E3 is a regular choice among design engineers for many of their electronic applications.
