Tantalum Capacitors

Tantalum capacitors are sometimes referred to as super capacitors, since they have the highest capacitance and energy density of any capacitor type. They are made from a ceramic material and capacitance is created by the dielectric layer between the two electrodes. The material used for the electrodes is usually tantalum or titanium for higher voltage applications.

M39003/01-2502 Application Field and Working Principle

The M39003/01-2502 is a capacitance-matched, hermetically sealed, highly reliable tantalum capacitor with a high temperature operating capability of up to +250°C. It is ideal for use in automotive, military, aerospace, and industrial applications, and provides excellent performance over wide operating temperatures.

The capacitor is constructed with a dielectric material that consists of a tantalum anode and a manganese oxide cathode. It is an electrolytic capacitor, meaning that the internal construction of the device requires the addition of electrolyte. The electrolyte is then used to form a dielectric layer between the two electrodes, which in turn creates the capacitance.

The working principle of the M39003/01-2502 is fairly simple. Since the device consists of two conductive plates, an anode and a cathode, separated by a dielectric layer, when a voltage is applied to the device, an electric field is formed that induces a charge on the plates, which in turn increases the capacitor\'s capacitance and energy density. When the voltage is removed, the capacitance and energy density will decrease to the original level.

The M39003/01-2502 is ideal for those applications where high temperature and reliable performance are needed. Its high working temperature capability enables it to be used in applications where regular capacitors may fail due to overheating.

Conclusion

The M39003/01-2502 is a high quality and reliable tantalum capacitor with a working temperature range of up to +250°C. It works on the basic principle of two conductive plates separated by a dielectric layer, which creates capacitance and energy density when a voltage is applied. Due to its excellent performance over wide temperature ranges, the M39003/01-2502 is an ideal choice for automotive, military, aerospace, and industrial applications.
