Aluminum Electrolytic Capacitors

Aluminum Electrolytic Capacitors are widely used components in electronic circuits for storing electrical energy and releasing it on demand. 338CKE035MQW is an aluminum electrolytic capacitor that is well-designed and suitable for applications where high capacitance value, long physical life, and excellent capacitance retention are essential.

338CKE035MQW Application Field and Working Principle

338CKE035MQW aluminum electrolytic capacitors are designed for general-purpose use in a range of applications, such as power supplies, stepper motors, electromagnetics, fluorescent lights, and many others. Due to its features, it is also suitable for temperature sensing and heavy-load applications.The capacitance of 338CKE035MQW Aluminum Electrolytic Capacitor is 35μF (+20% -80%) at a rated voltage of 6.3 VDC and a temperature rising time (TRA) of 85°C, which makes it robust and reliable. The dimensional size of the capacitor is 15.87 x 19.05mm. Additionally, the leakage current specification is 1mA or less at 6.3V DC, making it very efficient for various applications.When it comes to their working principle, the 338CKE035MQW aluminum electrolytic capacitors work similar to other electrolytic capacitors, in which an “anode” and a “cathode” are separated by a dielectric layer. In the case of the 338CKE035MQW, they are composed of a pair of aluminum foil sheets which are covered with an oxidizing agent in order to create the dielectric. The aluminum foil holds a positive charge (+) while the oxidizing agent has a negative (-) charge.When an electrical voltage is applied, positively charged particles move to the negative site and create a charge. This charge is built up between the two connections which can then be used to store energy until it is needed. The dielectric layer serves as separation between the two connections, allowing for an even distribution of the charge.

Advantages and Disadvantages

The advantages of the 338CKE035MQW aluminum electrolytic capacitors include its reliable performance, good capacitance retention, low ESR values, temperature compensation, and excellent peak surge handling capabilities. Furthermore, they are suitable for high-frequency applications and offer a long service life of 8000 hours or more when operated at 85°C.On the other hand, the major disadvantage of aluminum electrolytic capacitors is that they are prone to explosion or shortening if overstressed. They are also limited in their operating voltage, which is why they are generally used for low voltage applications. Additionally, these capacitors have a certain amount of leakage current, which is why they are not suitable for precision timing applications.

Conclusion

338CKE035MQW aluminum electrolytic capacitors are a reliable and efficient type of capacitor for general-purpose applications that require a high capacitance value, long physical life, and excellent capacitance retention. Although they have some disadvantages, such as a limited operating voltage, their advantages far outweigh these drawbacks. As a result, they are widely used across a variety of applications.
