Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are electrochemical components that rely on a thin layer of oxide film to store electrical energy. They are widely used in power supplies, box meters, audio playback and other circuits. The aluminum electrolytic capacitor models include LQSW6181MELA30.

The LQSW6181MELA30 is a cylindrical aluminum electrolytic capacitor with a long life, excellent characteristics, and a long use cycle. It has a rated volatge of 25V, a capacity of 1800 µF, and an operating temperature range of -25 ° C to 125 ° C. It has a pitch of 16mm and a diameter of 26mm. Its ripple current is about 145mA, and it has a rated endurance of 9000 hours. The LQSW6181MELA30 is RoHS compliant.

The LQSW6181MELA30 is made of an anode material composed of aluminum foil and a surrounding cathode foil composed of manganese dioxide and carbon particles. The anode and the cathode are electrically separated and electrolyte soaked paper is inserted in between. The separator has a thin layer of electrolyte that supports ionic conductivity. The electrolyte is a solution of potassium hydroxide which is spread between the anode and cathode as a thin layer which acts as an insulating barrier.

The LQSW6181MELA30 has a large capacitance and an excellent leakage performance and can effectively reduce the field interference to improve the stability of the circuit. The unit is small in size and can store large amounts of energy in the same volume. This makes them suitable for a wide range of applications in electronics, instrumentation and power supplies. The unit is well-suited for use in filtering circuits, bypass circuits and decoupling per-amplifier circuits. The unit is also able to withstand high-frequency interference, therefore it can be used in filtration systems as well.

The operating principle of the LQSW-6181MELA30 is simple. When the voltage is applied across the terminals, a current is induced in the electrolyte, causing the electrolyte to form a thin passivation layer on the anode. This passivation layer serves as an insulator, stabilizing the electrical charge in the anode and the cathode, and allowing electrons to move freely between the plates within the electrolyte. As current passes through the unit, it is stored on the anode and cathode plates in the form of electrical charge. This charge is then released as the voltage decreases and the capacitor is discharged.

In conclusion, the LQSW6181MELA30 is a high voltage 25V large capacity bipolar aluminum electrolytic capacitor. It has a small size and large capacity, making it suitable for use in various applications such as filtering, bypass, and decoupling circuits. The unit has an excellent life cycle, is RoHS compliant, and has a rated endurance of up to 9000 hours. The operating principle of the unit is simple, as it stores and releases electrical charge in an electrolyte when current passes through it.
