Tantalum capacitors are widely used in consumer electronics, automotive, industrial, and military electronics due to their small size, high capacitance, and long life. The M39003/01-8338H is a precision high-voltage, high-reliability tantalum polymer capacitor. It offers a higher level of performance than standard tantalum capacitors, with increased stability and reliability.

The M39003/01-8338H has an operating voltage range of 4.5V to 16V. It has an operating temperature range of -55°C to +125°C, and a temperature coefficient of ±10 parts per million per degree Celsius. Its operating temperature range makes it suitable for use in a wide variety of applications.

The M39003/01-8338H is ideal for high voltage switching power supplies, pulsed output converters, critical applications in military and aerospace, and other applications that require an electrically robust device. It offers high stability, wide temperature operation range, and long life.

The M39003/01-8338H includes a metalized polymer dielectric material, which allows for very low ESR (Equivalent Series Resistance) and ESL (Equivalent Series Inductance), and a high ripple current rating. This enables the capacitor to provide very high charge and discharge currents with minimal temperature rise and low power losses. The capacitor also includes an internal over-voltage protection circuit that prevents failure from occurring during high-voltage transients.

The operating principle of a tantalum capacitor is based on capacitance. Capacitance is the ability of an electrode to store an electrical charge. As a capacitor charges, it develops an electrostatic field, which is proportional to the electrical charge stored on the capacitor. The capacitor will discharge the stored energy in the form of an electric current. As the capacitor discharges, its electrostatic field decays, and the charge stored on the capacitor decreases.

Using a tantalum capacitor, the charge is stored in its dielectric material – a combination of tantalum and oxidized manganese dioxide. The two materials form a non-conductive dielectric (insulating) medium. When an alternating current (AC) is applied across the two terminals of the capacitor, the electric field induced by the alternating current causes charge to collect on the capacitor plates. This is known as the capacitance effect.

When the capacitance of the capacitor is increased, the voltage across the electrodes increases. As the voltage increases, current will flow through the capacitor. The current flow depends on the shape of the electrodes and the material inside the capacitor, as well as the amount of charge on the capacitance plates. With the M39003/01-8338H, the amount of charge stored on the capacitance plates is much larger than with standard tantalum capacitors.

The capacitance effect of the M39003/01-8338H also makes it ideal for use in switching power supplies, as it can store and release energy quickly. The fast discharge rate of the capacitor helps reduce electrical noise, as it reduces the voltage variations that can cause the circuit to malfunction. In addition, the high capacitance of the capacitor helps to increase the capacitor\'s ripple current rating, and the internal over-voltage protection circuit helps to protect it from sudden voltage spikes.

When combined with other components, the M39003/01-8338H can be used to design robust power supplies, improved and more reliable control circuitry, and more efficient and reliable switching power converters. The long life of the capacitor and its wide temperature range make it ideal for use in a variety of applications, from consumer electronics and automotive to military and aerospace.
