Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in various industries including automotive, telecommunications, audio-video, and computer industries, thanks to their good performance and low cost. The MAL211631338E3 model is an electrolytic capacitor developed by the Japanese Nippon Chemi-Con Corporation, and it belongs to this category. This paper will discuss the application field and the working principle of the MAL211631338E3 model.

Application Field

The MAL211631338E3 model is an aluminum electrolytic capacitor with a capacity of 10 micro-farads. It has a wide range of application fields, such as pulse circuits, audio circuits, and power supply circuits. It is also suitable for conditions with high temperature and high ripple current. As a radial-lead aluminum electrolytic capacitor, the MAL211631338E3 model can provide high reliability for harsh conditions from -25 degrees Celsius to 105 degrees Celsius.

Working Principle

Aluminum electrolytic capacitors are sometimes referred to as polarized capacitors due to their one-way operating principle – the anode must have a positive voltage, and the cathode must have a negative voltage. They consist of two metallic plates, one anode and one cathode, that are separated by a vinyl film. The anode plate is usually made of aluminum, coated with an oxide layer. The capacitor works by retaining charges between the anode and the cathode.

When voltage is applied to the capacitor, the anode of the capacitor becomes positively charged while the cathode becomes negatively charged. This causes a physical displacement of the electrolyte dielectric which can temporarily increase the capacitance of the capacitor. This increase can be as high as double the original capacitance. When the voltage is removed, the capacitor will return to its original capacitance.

The MAL211631338E3 model is a high-performance aluminum electrolytic capacitor with high ripple current and high temperature characteristics. It is well equipped with a 16V rated voltage and is very suitable for use in audio-video and computer applications. It also has a high capacitance density of 10uF and an excellent temperature characteristics of -25 to 105 degrees Celsius. In addition, it features low ESR (Equivalent Series Resistance) and low ESL (Equivalent Series Inductance) values.

In conclusion, the MAL211631338E3 model belongs to the aluminum electrolytic capacitor category, and it has several application fields, from audio circuits to pulse circuits. Moreover, its working principle involves the physical displacement of the electrolyte dielectric. In addition, it has a high rated voltage, a high capacitance density, and low ESR and ESL values.
