Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, often referred to as electrolytics, are capacitors with an electrolyte of aluminum foil, with a thin layer of oxidized aluminum on top of it, acting as the cathode. They are one of the most popular types of capacitors, as they can store a large amount of energy for a variety of different applications. The LPX681M250C4P3 is one of these capacitors, and is designed for use in power supplies, audio/video equipment, and instrumentation.

The LPX681M250C4P3 is a SMD Aluminum Electrolytic Capacitor with a maximum capacitance of 250µF, 260VDC, and a total height of 6.8mm. It has a rated voltage of 200VDC, rated ripple current of 2.8Arms, a rated temperature range of -40°C to +105°C, and a full pitch pitch distance of 5.08 mm. It is one of the most commonly used electrolytics for power supply and other applications due to its large capacitance and low profile.

Applications of the LPX681M250C4P3

The LPX681M250C4P3 is mainly used in power supplies due to its large capacitance and low profile. Its large capacitance allows it to store more energy than other capacitor types, and its low profile makes it ideal for applications where space is an issue. Other common applications for the capacitor include audio/video equipment, instrumentation, and motor control.

Working Principle of the LPX681M250C4P3

The working principle of the LPX681M250C4P3 is simple. When an electric current is applied, the aluminum foil acts as the anode, allowing electrons to pass through and transferring energy to the electrolyte. As the aluminum foil oxidizes, it forms an oxide layer, which acts as the cathode and prevents any more electrons from passing. This oxide layer also stores the energy that was originally transferred by the electric current, allowing the capacitor to maintain a potential difference between its two terminals.

As the LPX681M250C4P3 is a polarized capacitor, it needs to be properly connected to the device it is being used in. The positive terminal of the capacitor should be connected to the source, while the negative terminal should be connected to the ground. This connection ensures that the capacitor is absorbing energy from the source, and is able to properly store and supply it to other components.

Conclusion

The LPX681M250C4P3 is a popular aluminum electrolytic capacitor, due to its high capacitance and low profile. It is mainly used in power supplies, audio/video equipment, and instrumentation. The working principle of the capacitor is simple, as it stores energy by forming an oxide layer on the aluminum foil that acts as a cathode. Proper connections are important when using this capacitor in any device, as it is highly polarized.
