Aluminum electrolytic capacitors are widely use in electronics application. This article will focus on the application field and the working principle of EKZH250EC3102MJ25S, which is a kind of aluminum electrolytic capacitors.

EKZH250EC3102MJ25S is a radial capacitors with a telescopic housing. The cap is made with an aluminum can with a hinged lid, which provides a smooth transition between the capacitor’s metal contacts and the dielectric. The EKZH250EC3102MJ25S is an axial-leaded, 2-terminal, non-polarized electrolytic capacitor. It has a working voltage of 250V, an operating temperature range of -25°C and +105°C, and a highly stable capacitance value. It also has a long lifespan, with some models rated for over 100,000 hours.

The main application field of this aluminum electrolytic capacitor is in AC circuit power management, precision power supplies, instrumentation, switching power supplies and energy storage circuits. The capacitor can help to regulate the current in the circuit and reduce ripple in the power supply, thus improving the performance of the circuit.

The working principle of EKZH250EC3102MJ25S is based on the fact that two conductive surfaces separated by a layer of dielectric material form a capacitor. The aluminum electrolytic capacitor is constructed with a thin (typically 0.30mm) porous layer of oxide film which is formed on the surface of the aluminum cathode (a chemically active metal). An electrolyte (a solution of organic solvent and conductive ions) is added to the oxide film in a liquid or gel-like form, increasing the total surface area of the oxide film and enriching the contact between the aluminum cathode and the electrolyte.

The electrolyte acts as an ion bridge between the surfaces, enabling charge to be transferred from one surface to the other. The oxide film serves as the dielectric and enables the capacitor to store energy for future use. The entire construction is housed in an insulated sleeve, which prevents electrical shock and other damage to the capacitor.

EKZH250EC3102MJ25S aluminum electrolytic capacitors offer several advantages over traditional tantalum and ceramic capacitors. They are smaller in size and lighter in weight, thereby reducing the size and weight of the final product. They have a low ESR (equivalent series resistance) and ESL (equivalent series inductance), providing better power management, and they are very cost-effective. They also have a longer life expectancy, with some models rated for over 100,000 hours.

In conclusion, EKZH250EC3102MJ25S aluminum electrolytic capacitors are an ideal choice for AC circuit power management, precision power supplies, instrumentation, switching power supplies, and energy storage circuits. They offer excellent performance and reliability, with a long life expectancy, and are very cost-effective.
