Aluminum electrolytic capacitors have a wide variety of applications and uses due to their high capacitance and long service life. CGH702T250W4L is one of the various types of aluminum electrolytic capacitors, that has its own unique uses and application fields. This article provides a detailed overview of the application field and working principle of the CGH702T250W4L aluminum electrolytic capacitor, and should provide an informative and comprehensive description of the device.

Application Field of CGH702T250W4L

The CGH702T250W4L is a can-style aluminum electrolytic capacitor with a surface mount, making it suitable for applications where lower volume, height, and weight are desired. With a capacitance of 250 μF, voltage of 10 VDC, and ESR of 1.3 mΩ, this device is often used in circuits with low-frequency AC signal filtering under normal temperature. In addition, the CGH702T250W4L includes an external sleeve jacket for vibration and stress protection, making it suitable for applications which demand reliability and stability.

Typical application fields for the CGH702T250W4L aluminum electrolytic capacitor include instrumentation, consumer electronics, robotics, computer peripherals, automotive electronics, HVAC systems, and power factor correction. Its high capacitance, low ESR, and long life make it well-suited for these types of applications, providing efficient AC signal filtering.

Working Principle of CGH702T250W4L

The CGH702T250W4L aluminum electrolytic capacitor works on a simple principle. When a voltage is applied, a current passes through a pair of aluminum foils immersed in an electrolyte solution. This current creates an electric field between the two plates, causing ions from the electrolyte to be distributed in a pattern known as a Helmholtz Double-Layer. This double-layer forms a dielectric layer between the plates, providing the capacitance of the device. Since this dielectric layer can store electrical energy, the CGH702T250W4L can act as a capacitor.

The current passing through the device also causes a chemical reaction to occur between the two layers of aluminum foil, which forms a thin layer of aluminum oxide between the two plates. This oxide layer serves as a barrier that is capable of withstanding high voltages without breaking down. In addition, the device has a safety valve that prevents it from overheating and rupturing due to over-voltage.

The CGH702T250W4L aluminum electrolytic capacitor also has a relatively long life, estimated to be up to 1,000 hours depending on the frequency and amplitude of the applied voltage. The device is also moisture- and vibration-resistant, making it well-suited to applications in areas with high humidity or vibration.

Conclusion

The CGH702T250W4L aluminum electrolytic capacitor is a popular device, due to its high capacitance, low ESR, and long life. It is suitable for a wide range of applications, including instrumentation, robotics, and consumer electronics. Furthermore, the device is protected from mechanical vibration and moisture, making it reliable and safe to use in even the most challenging environments. Given its performance and robust design, the CGH702T250W4L aluminum electrolytic capacitor is ideal for low-frequency signal filtering applications.
