Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are a type of electrolytic capacitors, which are special polarised capacitors made with aluminum oxide film as the dielectric. Such capacitors are known for their small size and large capacitance in comparison to film capacitors. The most common type of aluminum electrolytic capacitor is usually referred to as a ‘leaky capacitor’ due to its tendency to lose charge despite a non-polarized connection.

The 108LBA200M2CG aluminum electrolytic capacitor is a useful capacitor for use in electronic applications, as it offers high capacitance values of up to 200µF, while occupying only a relatively small form factor. Such a capacitor offers a wide range of application possibilities depending on its purpose.

Some of the most common applications for the 108LBA200M2CG capacitor are in audio high frequency noise suppression, voltage stabilization, energy storage, snubber or by-pass application, and power factor correction. For these types of applications, the capacitor often needs to be large enough to store ample amounts of energy and the capacitance of the 108LBA200M2CG allows it to do this without taking up too much space.

The capacitor features a rated DC voltage of 100V, and it can also be used in ultra-high frequency noise suppression applications. It also offers a wide operating temperature range of -20 to +85°C. In surge conditions, its maximum surge voltage is 110V. For these features, the 108LBA200M2CG can be effectively used to reduce noise in frequencies up to 1MHz.

The working principle of the 108LBA200M2CG capacitor is based on the principle of electrolytic capacitance. This is a process in which an anode and a cathode are connected through an electrolyte, and separated by a dielectric material. This process allows electrons to freely pass through the electrolyte between the electrodes, generating a voltage across the device. This process is used to store energy, either in AC or DC circuit applications.

In order for the 108LBA200M2CG capacitor to work properly, the aluminum oxide film between the anode and cathode must be kept relatively thin, usually from 0.6 to 1 µm. This thin layer allows electrons to more easily move between the anode and the cathode, resulting in higher capacitance and lower voltage drop. Additionally, when used in AC applications, the capacitor benefits from a self-healing characteristic, which prevents a short circuit in the case of accidental physical damages.

In conclusion, the 108LBA200M2CG is a useful aluminium electrolytic capacitor offering comparatively large capacitance values for its small form factor. It is suitable for a wide range of applications such as audio noise suppression, voltage stabilization, energy storage, by-pass application, and power factor correction, and is ideal for use in ultra-high frequency noise suppression circuits. Its working principle is based on the electrolytic capacitance principle, which uses an anode, a cathode and a thin aluminum oxide film to store electrical energy.
