Tantalum Capacitors

Tantalum capacitors are a type of electrolytic capacitor – a passive electronic component that primarily consists of a metal cathode, an oxide cathode, and a non-polarized anode. They are primarily used in applications requiring high operating voltages as they can provide reliable performance in a wide range of temperature and voltage conditions. Tantalum capacitors are particularly suitable for use in digital circuits, as the recommended maximum operating voltage for them is 5V or 6V, and they offer excellent noise suppression and long-term stability.

M39003/01-2788/TR

The M39003/01-2788/TR tantalum capacitor is a radial-leaded anode device that has been manufactured in accordance with the MIL-PRF-39003 specification and is suitable for use as a high-density capacitor for general aviation and aerospace applications. This capacitor is designed for use in circuits operating up to a voltage of 10V, with an initial capacitance value of 1µF, Tolerance of ± 5% and a dissipation factor not exceeding 0.25%.

Application Field and Working Principle

The M39003/01-2788/TR capacitor is suitable for use in circuits such as DC-DC converters, power supplies, and high-frequency switches, as well as in other high-voltage applications where high ripple currents, high capacitance value stability, and low leakage currents are required. The working principle of the M39003/01-2788/TR is based on the electrostatic attraction of the positive and negative charges. The positive charge is stored in the anode and the negative charge on the oxide cathode. This creates a capacitive effect which stores electrical energy between the two plates and allows them to charge or discharge depending on the current flow.

The anode of the M39003/01-2788/TR is made of a high-temperature tantalum powder, and the oxide cathode is constructed of an oxide film. This combination creates a very reliable capacitor that is not susceptible to environmental factors such as temperature and humidity changes and is able to store a relatively high amount of energy for a given size. Additionally, the device is designed to withstand temperatures up to 125°C and has a maximum continuous operating voltage of 10V.

The M39003/01-2788/TR capacitor is an ideal component for high-voltage applications, offering excellent stability, long life, and high capacitance value in a small package.
