Tantalum capacitors, or tantalums, are a type of electrolytic capacitor. They are made up of a tantalum wire anode, an electrolytic solution, and a manganese dioxide cathode. This combination creates a device with a high capacitance to volumetric resistance ratio. As a result of this, tantalum capacitors are widely used in circuits for their ability to regulate the voltage in an electronic circuit and store energy. The M39003/01-7155H is a one platform system of tantalum capacitors made up of three capacitance elements for use in high voltage applications.

M39003/01-7155H Application Field and Working Principle

The M39003/01-7155H tantalum capacitors have a max operating voltage of 500V with a DC leakage current of 10uA max at 10 volts. The temperature range for these capacitors range from -55°C to +125°C. These capacitors are designed for use in high voltage circuits, such as those found in medical and telecom applications. They are also suitable for applications within the military or aerospace industries.

The M39003/01-7155H capacitors are reliable and have a uniquely low ESR suitable for modern digital circuits. They are also designed to be resistant to environmental impacts and mechanical shocks. As with all tantalum capacitors, the M39003/01-7155H capacitors rely upon a chemical reaction between the electrolyte and the metal substrate of the capacitor to create ions and provide a charge storage system. This chemical reaction is utilised to create the charge storing capacity of the capacitor, which is increased when a higher voltage is applied to the capacitor.

The M39003/01-7155H capacitor is intended to be connected between the positive and negative terminals of the circuit. The electrolyte then penetrates the insulation of the capacitor and contacts the metal wire, creating ions which are attracted to the positive terminal of the capacitor. As a result, an electric field forms between the positive and negative terminals, providing the capacitance and storage within the capacitor.

The amount of capacitance of the M39003/01-7155H is dependent on the size of the capacitor and its internal structure, as well as the voltage applied to the device. A higher voltage will create a larger electric field which results in increased capacitance. As the capacitor is utilised, the electric field will become weaker and the capacitance of the capacitor will begin to decrease.

The M39003/01-7155H capacitor uses a tantalum wire anode and cathode which has been specially designed for use in high voltage applications. The anode is formed from a high-grade tantalum wire which is coated with a slightly thicker layer of manganese dioxide. This layer allows for current to pass through the anode while protecting it from corrosion.

The cathode of the M39003/01-7155H capacitor is a solid manganese dioxide which provides an electrical connection to the positive terminal of the capacitor. This allows for the transfer of electrical energy to the device. The electrolytic solution then penetrates the manganese dioxide and forms the ions necessary for the storage of energy within the capacitor.

In conclusion, the M39003/01-7155H tantalum capacitor is designed for use in high voltage applications such as those found in aerospace, medical, and military equipment. The use of a tantalum wire anode and manganese dioxide cathode provide a low ESR with a reliable working temperature range of -55°C to +125°C. The strong electric field formed by the anode and cathode provides the necessary capacitance for storing energy within the device.
