Aluminum Electrolytic Capacitors

Introduction

Aluminum electrolytic capacitors are the most commonly used type of capacitors. They consist of two thin aluminum foils, one of which is rolled in a cylinder and covered with an insulating material. This material is called the dielectric and it is often a paper infiltrated with electrolyte. Aluminum electrolytic capacitors contain an electrolyte, usually an acidic solution, and the aluminum foils are plated with an oxide layer. The electrolytic capacitors are polarized, meaning they have a Positive and Negative side and must be connected to the proper polarity.

200SAW150MEFC18X20 application field and working principle

200SAW150MEFC18X20 is a type of aluminum electrolytic capacitor. It is a miniature electrolytic capacitor specifically designed for use in high-current applications and high-voltage operation. The capacitor has a diameter of 18mm and a height of 20mm, making it ideal for applications where space is limited. It has a rated capacitance of 150µF and a rated voltage of 200V, making it ideal for high voltage and high current applications.

200SAW150MEFC18X20 works by storing energy in the form of electrical charge. The capacitor is made up of two conductive plates, one of which is insulated from the other, that are separated by a dielectric. When a voltage is applied across the terminals of the capacitor, electrons accumulate on one of the plates creating a negative charge. This in turn creates a positive charge on the other plate due to the attraction of opposite charges. This stored charge can then be used when needed.

The 200SAW150MEFC18X20 is used in a wide variety of applications, including ignition systems in vehicles, UPS systems, motor controls, power supplies, and audio equipment. It is also commonly used in RF (radio frequency) and EMI (electromagnetic interference) filtering applications. The capacitor is also used as energy storage in start/stop systems, high/low voltage switchgear, and surge protection circuits.

Conclusion

The 200SAW150MEFC18X20 is an aluminum electrolytic capacitor that is ideal for use in high-current and high-voltage applications where space is limited. It has a capacitance of 150µF and a rated voltage of 200V, making it suitable for a variety of applications. The capacitor works by storing energy in the form of electrical charge and can be used for a wide range of applications, including vehicle ignition systems, UPS systems, motor controls, and power supplies.
