Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in commercial and industrial electronic equipment, especially as the main energy storage devices for power supplies. Their capacitance and reliability make them suitable for use in switching power supplies, power line regulation/filtering, and signal filtering. They are also used for audio and radio frequency applications, resonant circuits, general power supplies, and time delay systems.

The TCG202U025N1L capacitor is a surface-mount aluminum electrolytic capacitor featuring a non-polar designs. It is ideal for use in harsh environmental conditions and high-frequency applications. The operating temperature range of this capacitor is -55°C to +105°C. Its maximum capacitance value is 3.5 microfarads, and its rated voltage is 25 Volts.

Function and Working Principle

The TCG202U025N1L capacitor is a surface-mount aluminum electrolytic capacitor which works on a process known as electrolysis. An electrolytic capacitor contains an anode which is made from aluminum foil. The aluminum anode becomes oxidized when exposed to oxygen in the air. This oxidation creates a thin layer of oxide which acts as the dielectric. This layer has the remarkable ability to store large amounts of electrical energy.

When a voltage is applied across the capacitor, electrons from the positive terminal travel to the anode via the oxide layer. This creates an electric field and charges the capacitor. The oxide layer also prevents the electrons from returning to the negative terminal which keeps the capacitor charged. The oxide layer also prevents the electrons from passing through which leads to a high capacitance value.

Thus, the TCG202U025N1L capacitor offers excellent performance in terms of ripple current, equivalent series resistance (ESR), and noise suppression. Its various characteristics such as surge resistance, ripple current rating, and low impedance make it suitable for use in high-frequency applications. The capacitor is also resistant to vibration and has a long operating life. All these features make it an ideal choice for use in a variety of electronic equipment.
