Tantalum Capacitors: M39003/03-2079H Application Field and Working Principle

Tantalum capacitors are commonly used electronic components with the ability to store energy in an electric field. They are a type of capacitor, created by using tantalum oxide dielectric material on top of two metallic electrodes. The electrodes provide the capacitor with increased electrical conductivity and stability, enabling it to store energy even when it is not being actively charged or discharged. In most cases, tantalum capacitors are smaller compared to other types of capacitors.

The M39003/03-2079H is an aerospace grade capacitors that offers a combination of durability, reliability, and performance for various military aircraft requirements. It meets the performance and temperature ratings for aerospace applications. It offers an operating temperature range from -55°C to 85°C, and a shelf life of up to 10 years. Its construction features a solid tantalum anode and a manganese-based oxide cathode. It also offers a high rated voltage of up to 16 VDC.

Regarding its application field, M39003/03-2079H capacitors are primarily used in high-temperature aerospace applications as filter capacitors in areas such as avionics, instrumentation, radar, and communication systems. Its higher voltage rating makes them suitable for replacing electrolytic capacitors in some instances.
