Aluminum electrolytic capacitors are devices that store, filter and regulate voltage in electric circuits. They are composed of two aluminum foils that are separated by a hydrophilic insulating layer, usually composed of paper and sometimes organic polymer. One of the foils is etched away, forming a porous structure that is coated with an electrolyte called manganese dioxide. The other foil is sealed, forming a capacitor that is often marked with a three-digit code. The code of interest in this discussion is 381LX562M063K452, which belongs to a family of capacitors commonly known as “Multi-Layer Ceramic Chip” capacitors.

In terms of application field, MLCCs are useful as protection components that protect circuits from voltage changes, spikes and surges, allowing for stable current and signal flow. Their small size also makes them ideal for use in space-constrained applications. They are used extensively in consumer electronics, automotive applications and industrial control systems.

The 381LX562M063K452 is a multi-layer chip capacitor with a temperature coefficient of +125 -55 ppm/°C and a rated voltage of 50 VDC. The device is composed of a dielectric layer sandwiched between two metallized electrodes. The dielectric layer is made of a ceramic material that is etched away, creating a porous layer that is then filled with a conductive polymer. This porous layer acts as the second layer of electrodes, giving the capacitor its multilayer structure and increased capacitance.

The working principle of MLCCs is straightforward. When a voltage is applied to the device, the porous layer creates an electric field, which causes a charge to accumulate on one side of the chip, generating a capacitive reactance. This capacitive reactance works in combination with the voltage to create a current that is stored in the circuit and can be used to regulate voltage and current flow. When the voltage is removed, the charge dissipates, returning the capacitor to its original state.

Given its small size, versatility, and ability to provide protection against voltage changes, surges, and spikes, the 381LX562M063K452 aluminum electrolytic capacitor is an invaluable component for many practical applications. Its application field and working principle make it a versatile and dependable device in both consumer electronics and industrial settings.
