Tantalum capacitors, a type of electrolytic capacitor, are widely used in electronics due to their high volumetric efficiency, long-term stability, and excellent noise reduction characteristics. The M39003/01-5691/TR is a series of tantalum capacitors and comes in both axial and radial leaded package configurations.

A tantalum capacitor consists of a small cylindrical anode and a larger cylindrical cathode, both made of conductive materials. During manufacture, the anode of the capacitor is immersed in a bath of tantalum pentoxide (Ta2O5) suspended in isopropyl alcohol (IPA). The electrical field that is generated between the two electrodes forms a thin oxide layer across the anode surfaces which functions as the dielectric. This dielectric effectively separates the two conductors allowing the capacitor to store electrical energy, making it an ideal solution for high-density applications.

M39003/01-5691/TR capacitors have a wide range of applications due in part to their low ESR (equivalent series resistance) and high capacitance. Common applications include power converters, DC/DC converters, oscillators, and pulse generators. They are especially suitable for high-reliability/high-stability applications such as missile guidance, telecommunication, and networking.

M39003/01-5691/TR capacitors have two main working principles. The first is capacitance. When a voltage is applied to the two electrodes, the electric field created between the two electrodes causes a charge (or a potential difference) to build up between them. The charge is stored in the dielectric layer, which is then released when the voltage is removed.

The second principle is Equivalent Series Resistance (ESR). The ESR is the resistance encountered when an alternating current (AC) passes through the capacitor, as the dielectric does not provide a perfect insulation. The ESR is very low for M39003/01-5691/TR capacitors, which allows them to store more energy while producing less noise in the circuit.

In summary, the M39003/01-5691/TR capacitor series from Tantalum are specialized capacitors designed for applications where long-term reliability, high-stability, and superior noise reduction are essential. The two key working principles of these capacitors are capacitance and ESR. With a wide range of applications and excellent performance, M39003/01-5691/TR tantalum capacitors are a popular choice for many high-reliability applications.
