Tantalum capacitors, also known as tantalum electrolytic capacitors, are electronic components used to store energy electrically in an electronic circuit. The M39003/01-6030 is a type of tantalum capacitor specified by the military and designed for special purposes such as military equipment. It is typically used in high frequency, high temperature, and hostile environments where standard commercial components may not perform.

The M39003/01-6030 is a polarized capacitor with an anode and a cathode terminal. It has a leakage current between 5µA and 30µA at 25°C to 65°C, a capacitance of 0.015 µF to 0.1 µF, maximum working voltage of 15V, and a maximum operating temperature of 125°C.

The M39003/01-6030 is designed for use in military and aerospace applications such as radar, communications, and navigation systems. It is designed to meet all the requirements of MIL-PRF-39019/161 and is supremely reliable and versatile for a range of applications. Because of its higher voltage ratings and lower leakage currents, it is also used in high-frequency switching power supplies.

The working principle of a tantalum capacitor is similar to that of an electrolytic capacitor. Electrons move from the anode to the cathode when a voltage is applied, and electrons move from the cathode to the anode when the voltage is reversed. This action creates a potential difference between the two terminals and stores within the capacitor electrical energy.

The anode of the M39003/01-6030 is typically a foil of anionic tantalum oxide. It is then heated up to around 500°C and then poured into a manganese dioxide powder, which acts as an electrolyte. The cathode is a non-conductive material such as epoxy resin which separates the anode and the manganese dioxide powder. This creates a barrier between the two terminals and helps maintain a stable voltage.

The capacitance of the M39003/01-6030 can be adjusted by changing the size of the anode and the thickness of the dielectric, which is the manganese dioxide. By decreasing its thickness, the capacitance of the capacitor increases. It is also possible to increase the capacitance of a capacitor by adding a second anode and increasing the amount of manganese dioxide.

In conclusion, the M39003/01-6030 is a type of tantalum capacitor designed for special applications in military and aerospace applications. Its working principle is similar to that of an electrolytic capacitor and its capacitance can be adjusted by changing the anode size and thickness of the dielectric.
