Tantalum capacitors have been widely used in the electronics industry due to their wide range of applications and excellent performance. The M39003/03-0464H capacitor is an example of a tantalum electrolytic capacitor that is suitable for high current and high-temperature applications. In this article, we will discuss the application field and working principle of the M39003/03-0464H capacitor.

Application Field

The M39003/03-0464H capacitor is designed for use in high current or high temperature applications. It has a high maximum ripple current of up to 4.6A, which makes it ideal for power supply circuits. It also has a high operating temperature range of -55°C to +125°C which makes it suitable for use in industrial and automotive electronics. This capacitor is also suitable for use in high-end audio and video circuits, where its high pulse capability allows for more accurate sound reproduction and better picture quality.

The M39003/03-0464H capacitor is also widely used in military and aerospace applications, where its high ripple current and temperature rating make it suitable for high power, high temperature and high voltage systems. This capacitor is also used in air conditioning and refrigeration systems, where it helps to ensure reliable operation in extreme temperatures.

Working Principle

The M39003/03-0464H capacitor is an electrolytic tantalum capacitor, which consists of a piece of sintered tantalum and two electrolytes. The electrolytes are separated from the metal by a thin dielectric layer called a separating layer. The capacitor works by passing current between the two electrolytes. The positive electrode (anode) charges up, while the negative electrode (cathode) discharges. The flow of charge and the capacitance of the capacitor depend on the distance between the two electrolytes.

The M39003/03-0464H capacitor has a special feature known as “Enhanced Surge Immunity”, which means that it can handle higher surge currents compared to other tantalum capacitors. This increased surge current capability is achieved by increasing the surface area of the anode and cathode, resulting in faster charging and discharging times.

In order to increase the maximum ripple current and temperature range of the M39003/03-0464H capacitor, it is constructed using a thicker anode/cathode separation and faster charging times. This allows it to handle large surges of current and to operate in high temperature conditions.

Conclusion

In conclusion, the M39003/03-0464H capacitor is an electrolytic tantalum capacitor that is designed for high current and high temperature applications. It has a high maximum ripple current of up to 4.6A, and a high operating temperature range of -55°C to +125°C. It is widely used in power supply circuits, audio/video systems, and military/aerospace applications. The “Enhanced Surge Immunity” feature allows the capacitor to handle higher surge currents, while the thicker anode/cathode separation enables it to operate in high temperature conditions.
