Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are among the most commonly used capacitors in the world, due to their low cost and high performance capabilities. They are also referred to as “tantalum” or “tantalum-coated” capacitors.

The E37L351CPN392MDB7M is an aluminum electrolytic capacitor designed for use in a wide variety of applications, including general-purpose power supplies, consumer electronics, and industrial electronics. It is also ideal for use in motor control systems, voltage regulators, and other critical applications that require strong performance and reliability.

The E37L351CPN392MDB7M aluminum electrolytic capacitor features a rated voltage of 35V, a maximum ripple current of 3.2 A at 100 kHz, and a maximum working voltage of 50V. It has a very low ESR of < 0.2 Ω, which makes it ideal for applications that require both low voltage and high ripple current. It also features a low self-inductance and an ultra-high capacitance of 125 mF, making it ideal for applications that require high-frequency filtering or transient suppression.

Working Principle

An aluminum electrolytic capacitor consists of an anode, an electrolyte, and a capacitor plate or plates. The anode is made of an aluminum foil, while the electrolyte is typically a mixture of ethyl alcohol and KOH. The capacitor plate is formed when the electrolyte is absorbed and precipitated on the anode surface.

When an electric potential is applied across the capacitor, a current is generated, which causes ions from the electrolyte to move toward the anode. This creates a layer of electrolyte which acts as an insulator between the anode and the capacitor plate. The electric field produced by the current causes ions to move from the anode to the capacitor plate which increases the capacitance.
