Tantalum capacitors are a type of capacitor that is generally made up of tantalum metal, which serves as the anode, and a coating of metal oxide which acts as the cathode. M39003/01-2503H is one such type of tantalum capacitors. This capacitor is designed for switching and pulsed applications in military and other high reliability applications, such as aerospace, computer peripherals, and instrumentation.

M39003/01-2503H has a polarized aluminum electrolytic capacitor attached to the positive lead, offering superior temperature sensitivity performance, and providing good EMI radiation characteristics, with low effective series inductance. This capacitor also provides high reliability, and allows for operating up to 125°C.

The working principle of M39003/01-2503H is that it has a thin layer of tantalum pentoxide, which serves as the dielectric for the device. This is attached to a cathode material, such as manganese dioxide, and a gaseous electrolyte. During operation, the cell is charged at the anode, and the current flows from the positive to the negative electrodes. The manganese dioxide reacts with the electrolyte, and adsorbs ions in order to form a negatively charged dielectric layer. The capacitance is determined by the area of the metal oxide film and the applied voltage.

The M39003/01-2503H application field includes defense and military applications, such as aircraft and missile guidance systems and satellite navigation. It can also be used for commercial applications, like telecommunications, radios, and medical instruments, as well as industrial applications, like power supply control boards and industrial automation systems. This capacitor is useful for high pulse current and high temperature application, and can provide a long and reliable service life when applied correctly.

In conclusion, M39003/01-2503H is a type of tantalum capacitor that offers superior temperature sensitivity performance and high reliability. It is widely used in defense and military, commercial and industrial applications, and can withstand high pulse current and high temperatures with a reliable long life performance.
