Tantalum capacitors are a type of electrolytic capacitor which uses tantalum as an active material in its anode layer. They are widely used in many electronic applications due to their high volumetric efficiency, long life, low temperature coefficient and DC leakage characteristics. The M39003/09-4062 is a surface-mount tantalum capacitor and is specifically designed for high frequency applications.

The M39003/09-4062 is an axial-leaded, high frequency, low ESR tantalum capacitor with a case material of ceramic, an anode of tantalum, and a cathode of manganese dioxide. The device is rated for a capacitance range of 0.1 to 2.2μF, and a voltage range of 6.3 to 16VDC.

The M39003/09-4062 is typically used in applications such as DC to DC converters, high voltage power supplies, inverters, and pulse filters which require high energy density. It is also used in portable applications that require low to medium ESR, such as cell phones and digital cameras. In telecommunications and datacom equipment, it is used for timing circuits, filters, and noise suppression.

The M39003/09-4062 has a unique cathode construction which enables it to produce higher capacitance values at a given ESR. The capacitor also provides good insulation against dielectric absorption and improves the device stability. Additionally, its ultra-low ESR characteristics enable it to reach out to higher frequencies and provide excellent ripple suppression capabilities.

The working principle of the M39003/09-4062 is based on the idea that when a voltage is applied across two plates which are separated by an insulating material, a capacitive charge will be produced between the two plates and stored in the ceramic dielectric. The capacitor is initially charged with a voltage of 6.3V, and when the voltage exceeds 16V the charge is dissipated and the capacitor is reset. This charge is retained for a long period of time, and the capacitor can be reactivated by re-applying the charge.

Overall, the M39003/09-4062 is an ideal option for high frequency applications that require a moderately low ESR and good ripple suppression capabilities. The device provides a good balance between capacitance and ESR, and its long-term stability make it a suitable choice for applications requiring long lifetimes and low power dissipation. Its wide voltage range, low leakage currents, and high energy density also make it a great choice for portable and telecom applications.
