Tantalum capacitors, also known as tantalum electrolytic capacitors, are a type of electrolytic capacitor that uses tantalum as its anode and are usually divided into two types, wet tantalum capacitors and solid tantalum capacitors.

The M39006/25-0068 is an example of a wet tantalum capacitor. It is a hermetically sealed, large and low profile, radial leaded device, mainly used in automotive and computer applications, which are capable of withstanding long-term operation at rated voltage and temperature. The capacitance of this device is between several picofarads and several hundred microfarads.

The working principle of the M39006/25-0068 is the same as other wet tantalum capacitors. It is essentially an electrolytic capacitor that uses tantalum as its anode and uses an electrolyte (aqueous manganese dioxide) as the cathode to form the capacitor with a dielectric oxide layer on the tantalum surface as the dielectric medium. The electrolyte is held in a sealed tank with a polarized electrical connection and two terminals on either side of the tank. The anode is connected to the positive terminal and the cathode is connected to the negative terminal. When a voltage is applied to the device, the electrolyte reacts with the tantalum anode, forming an oxide layer on its surface. The capacitance of the device is determined by the thickness and area of this oxide layer, the type of electrolyte used, and the amount of electrical charge passed between the two terminals.

The M39006/25-0068 is predominantly employed in automotive and computer applications, primarily due to its hermetically sealed design which prevents moisture and contaminants from entering the circuit, as well as its low profile/small size which makes it suitable for use in confined and cramped spaces. It is also suitable for use in applications where low leakage current and high capacitance are required, such as automated test systems and vibration rigs.

Overall, the M39006/25-0068 is a reliable and efficient wet tantalum capacitor capable of withstanding long-term operation at specified voltage and temperature. It is suitable for use in automotive and computer applications as well as automated test and vibration rigs, due to its hermetically sealed design and its low profile/small size. Its working principle is the same as other wet tantalum capacitors, with its capacitance determined by the thickness and area of the oxide layer on the tantalum surface, as well as the type of electrolyte and amount of electrical charge passed between the two terminals.
