Introduction to Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor, commonly known as an electronics grade capacitor, is an electronic component made up of two metal plates separated by an electrolyte material, such as an oxide of aluminum. It’s known for its high capacitance, wide operating temperature range and long life. Aluminum electrolytic capacitors are used in many electronic devices, including power supplies, motors, TV sets, and more.

Special Features of 128LMX250M2EH

The 128LMX250M2EH aluminum electrolytic capacitors are part of the series of advanced high-temperature capacitors with axial lead spacing. The capacitors are made with aluminum electrodes, offering outstanding features such as high performance, long life, and high reliability.The 128LMX250M2EH aluminum electrolytic capacitors are designed to provide an effective yet affordable solution for high-temperature applications. These capacitors are engineered to provide high capacitance and low ESR, making them ideal for coupling, bypass, and filter applications at high frequencies.

Application Field and Working Principle of 128LMX250M2EH

The 128LMX250M2EH aluminum electrolytic capacitors are suitable for a variety of applications that require high temperature and vibration tolerance, such as communications, power supplies, switch-mode power supplies (SMPS), industrial equipment, and other commercial applications.The capacitors use a special anode oxide layer and solid electrolyte conductor to achieve low equivalent series resistance (ESR) and high ripple current. This is combined with tight tolerances on capacitance, leakage current, and resistivity.The working principle is based on the electro-chemical process that occurs when the capacitor is placed in direct contact with an electrolyte material. When a voltage is applied to the capacitor, an electrical current is produced, which ionizes the electrolyte and generates an electric field across the plates of the capacitor, resulting in the electrical energy being stored in the form of an electric charge. This electric charge can then be drawn off as energy when the capacitor is connected to a load.

Conclusion

The 128LMX250M2EH aluminum electrolytic capacitors are designed to provide an effective, affordable solution for high-temperature applications. Their robust design and construction, combined with their low ESR and high current ratings, make the capacitors ideal for applications in the communications, industrial, and other commercial fields. The electro-chemical process employed in these capacitors ensures a reliable and repeatable operation for extended periods.
