Tantalum Capacitors: M39003/03-2035 Application Field and Working Principle

Tantalum capacitors are a type of electrolytic capacitor, and they are widely used within the electronics industry. They offer a variety of advantages over other types of capacitor, including higher capacity in a small, lightweight package. The M39003/03-2035 is a tantalum capacitors made specifically for high-reliability military and aerospace applications. This article will explore the application field and working principle of this capacitors for use in these industries.

Application Field for M39003/03-2035 Tantalum Capacitors

The M39003/03-2035 is designed for use in high-reliability military and aerospace applications. They offer several distinct advantages over other types of capacitors in these applications. First, their size and weight mean that they don’t take up much room, which is important in certain military applications. Additionally, they provide higher capacity in a smaller package than other capacitors, which can be a critical factor when space and weight are at a premium. Finally, their reliability and long life span make them suitable for use in applications that require a lengthy life expectancy and maximum performance.

Some of the most common uses of the M39003/03-2035 in aerospace and military applications include:

• Power supply regulation
• Noise suppression
• High-frequency pulse width modulation
• Signal filtering
• High-voltage snubbing

The M39003/03-2035 is also suitable for use in automotive, communications, and industrial applications. Additionally, it is approved for use in UL Recognized/CSA Certified designs.

Working Principle

Like other types of electrolytic capacitors, the M39003/03-2035 is composed of two metal plates separated by an electrolyte. One plate is made of a special conducting material, such as tantalum, while the other is made of a more conductive material, such as aluminum. An electric current is applied to the two plates, causing the electrolyte to form an insulating barrier between them. This barrier, which is also called the “dielectric,” forms the capacitor’s capacitance or ability to store electricity.

The capacitance of the M39003/03-2035 is further enhanced by the use of a polymer electrolyte that is highly viscous, which eliminates the need for additional dielectrics. The capacitance offered by this type of capacitor is much higher than that offered by other types of electrolytic capacitors, allowing for a smaller size and weight. The working temperature range is -55℃ to +125℃, making the capacitor suitable for use in a wide variety of temperatures.

Conclusion

The M39003/03-2035 is a high-reliability tantalum capacitor made specifically for military and aerospace applications. It offers a number of advantages, including high capacitance in a small package, high reliability and long life span. By understanding its application field and working principle, one can appreciate the benefits it can offer to users in the military and aerospace industries.
