Aluminum electrolytic capacitors, which are sometimes referred to as wet electrolytic capacitors, use an electrolyte consisting of alcohol and glycol to store electrical energy. The aluminum electrolytic capacitor is made of two electrodes made from aluminum foil. A spacer, made of a non-conductive material, is inserted between the electrodes. On one side of the spacer, the aluminum foil is chemically etched to create an oxide layer that acts as a dielectric. The other side of the spacer is covered with an absorbent material called a manganese-dioxide electrolyte.

The M39018/04-1124 is a type of aluminum electrolytic capacitor that is especially useful in fields such as audio, radio, and system power supplies. The aluminum electrolytic capacitor is designed to provide protection against reactive power disturbances caused by excessive voltages, current overloads, high-frequency impulses, and lightning strikes. The M39018/04-1124 is available in both radial and axial leaded versions.

The M39018/04-1124 aluminum electrolytic capictor has a wide temperature range, with voltage ratings of 25 to 450 volts DC, and capacitance values up to 400 mF. It is ideal for applications where high capacitance, low ESR, long life, and wide operating temperature ranges are required. This capacitor can also be used in demanding applications requiring low leakage currents of 1 µA and high ripple current capability of + 8.4A at 100 kHz.

The working principle of an aluminum electrolytic capacitor is largely dependent on the physical construction of the capacitor. Each capacitor consists of two plates that are constructed from tin-plated aluminum foil. In between these two plates is a dielectric made of aluminum oxide, which is formed when the surface of the aluminum foil is treated with an electrolytic process. The dielectric allows for the capacitor to hold a charge.

When a voltage is applied across the terminals of the capacitor, the electric field between the two plates will cause a current to flow. This current flow creates a static charge at each plate, which develops a potential between them. This potential maintains the charge in the capacitor. The resistance between the plates is relatively small, so that current can flow for a long time without significant power losses.

As with all capacitors, the M39018/04-1124 aluminum electrolytic capacitor must be discharged before it can be removed from the circuit. The capacitor must be discharged by shorting its terminals together or by connecting it to a large resistor. This will allow the stored charge to dissipate, thus avoiding the risk of electric shock or damage to the capacitor.

The aluminum electrolytic capacitor is a critical component in many electrical and electronic circuits. The M39018/04-1124 aluminum electrolytic capacitor is a reliable and cost-effective option for applications where high capacitance, low ESR, long life, and wide operating temperature ranges are required. Its wide temperature range and voltage ratings make it suitable for use in a variety of applications, including audio, radio, and system power supplies.
