The sizes range from 0201 to 1210 for commercial and military applications respectively. The capacitor also has a maximum rated ripple current which ranges from 2.7 to 4.4 mA.

Working Principle

The M39003/01-2748 is a surface-mount (SM) tantalum capacitor. It consists of a tantalum anode, a dielectric and a cathode. The main principle behind its functioning is a static electric charge. When a voltage is applied across the two terminals, the dielectric becomes conductive. This sets up an electric field between the anode and the cathode. This electric field causes the electrons to move from the anode to the cathode and produce an electric current. This current is stored in the capacitor in the form of a static electric charge.

The capacitor also has a built-in self-repair mechanism. Whenever the capacitor is subjected to a voltage excursion or an overload, the tantalum anode forms a solid layer on the internal dielectric material. This layer helps to restore the electric field and thus reduces the risk of capacitor failure due to overloads.

Conclusion

M39003/01-2748 is a surface-mount tantalum capacitor and is used in a variety of electronic applications. It is ideal for use in military and aerospace applications due to its wide temperature range. The capacitor is available in various sizes and configurations and has a maximum rated ripple current ranging from 2.7 to 4.4 mA. It also has a built-in self-repair mechanism which helps to reduce the risk of capacitor failure due to overloads.
