Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are coaxial capacitors used in a wide range of applications ranging from simple non-power circuits to power supply circuits. The properties of aluminum electrolytic capacitors such as their relatively high capacitance, low cost, and small size make them an attractive choice for many applications. They are often used to provide filtering, decoupling, and energy storage in electronics circuits.

250MXC820MEFC35X35 Application Field and Working Principle

The 250MXC820MEFC35X35 is a long life, miniature snap-in aluminum electrolytic capacitor. It is designed for use in switching power supplies and other automated control applications where compactness and reliability are essential. This capacitor is rated for a capacitance of 820µF at a working voltage of 35V and can be used in temperatures ranging from -40°C to +105°C. This capacitor has a high ripple current rating of 60A, a low ESR rating of 10mΩ at 100KHz, and an extended life of 2000 hours at +105°C.

Aluminum electrolytic capacitors rely on the voltage stabilization of an oxide film on the capacitor’s anode. This voltage stabilization is necessary due to the fragility of the oxide film, and is why aluminum electrolytic capacitors must be connected with the correct polarity. Without proper polarity, the voltage applied across the capacitor’s plates would be reversed and the oxide film would be damaged.

The 250MXC820MEFC35X35 is suitable for a wide range of applications, including power supply filtering, energy storage, and high-frequency decoupling. Its high ripple current capability and long life make it ideal for use in switching power supplies and automated control applications. It is also well suited for high frequency circuits where its low ESR rated helps to reduce loss and improve noise reduction.

The 250MXC820MEFC35X35 also has exceptional performance when used in clamping and limiting circuits. Its excellent temperature and voltage coefficient enable it to maintain a high level of stability even when subject to extreme temperature variations and high shock levels. This makes it extremely reliable and suitable for use in applications with a high degree of operational safety and reliability.

Conclusion

The 250MXC820MEFC35X35 is an excellent choice for a wide range of applications which require high-performance aluminum electrolytic capacitors. Its long life, high ripple current rating, low ESR rating, and excellent temperature and voltage coefficient make it an ideal choice for a wide range of power supply filtering, energy storage, and high-frequency decoupling applications. It is also reliable and suitable for use in applications with a high degree of operational safety and reliability.
