Tantalum Capacitors

Tantalum capacitors are electronic components that use tantalum ore as the electrolyte. By combining the tantalum as an anode material, electrolyte and separator, a capacitor is created. The tantalum capacitor has extremely high volumetric efficiency, small size, and high capacitance for its size. Its volumetric efficiency is fifty times that of the aluminum electrolytic capacitor, and they have a QR of 30,000 to 400,000 times over that of the aluminum electrolytic capacitor.

The cost of the tantalum capacitor is much higher than that of the aluminum electrolytic capacitor, but its stability and reliability make it particularly suitable for extreme environment applications such as aerospace, medical and military industries.

M39003/01-8194/99 working principle

As with all tantalum capacitors, the M39003/01-8194/99 has two terminals, one connected to the anode and the other connected to the cathode. The anode of the capacitor is made of the given oxide, and the cathode is made of tantalum. The tantalum is immersed in an electrolytic liquid, and on the top of the electrolytic liquid is a separator. When a voltage is applied between the anode and the cathode, the ions present in the electrolyte is attracted to the anode and the electrons present in the electrolyte is attracted to the cathode. This separation of charges causes a charge to build up at the anode and cathode, creating a capacitance in the capacitor.

The M39003/01-8194/99 has a rated capacitance of 0.22μF and a rated voltage of 35V. It has a wide temperature range of -55 °C to +85 °C and can withstand frequent operating temperature changes as well as sudden changes in the surrounding environment. This makes it suitable for applications where the environment can vary frequently.

The M39003/01-8194/99 is a reliable and stable capacitor that provides excellent performance in extreme environment applications. With its small size and high volumetric efficiency, it is a perfect choice for portable and miniature electronics applications.
