Tantalum capacitors are a type of electronic component used to store electric charge. The M39003/01-5018 is an axial lead tantalum capacitor used in a variety of applications in the electronics industry. It consists of a MnO₂ anode, a tantalum oxide dielectric, a silver-palladium outer anode and is impregnated with a non-aqueous electrolyte. This capacitor is ideal for use in applications where space is at a premium, and reliability and long life are desired.

The application field of the M39003/01-5018 encompasses high frequency N-type filters, timing circuits, sample and hold circuits, computer logic circuits, digital signal processing circuits and memory devices. The application area could include any device requiring a frequency-selective capacitor such as a radio receiver/transmitter, through-hole capacitor for surface-mount components, and many more.

The working principle of the M39003/01-5018 is based on Faraday’s law of electrostatic induction. When an electric field is applied across two conductors separated by an insulating dielectric material, an electric charge is stored on the insulator, creating a capacitance. This capacitance increases proportionally with the area of the conductors and inversely with the distance between them. The application of an electric field causes electrons to flow, creating an electric current which stores energy in the form of an electrical charge.

In the M39003/01-5018, the two conductors consist of the cathode and the anode, separated by a dielectric of tantalum oxide. The anode is usually made of silver-palladium, a material mix that ensures lower series resistance and superior heat resistance. The capacitor can retain an increased amount of charge due to the presence of a non-aqueous electrolyte. This electrolyte is made up of a mixture of salts that dissociate into free ions when a voltage is applied, thus improving the capacitance of the capacitor.

The M39003/01-5018 tantalum capacitor is rugged, lightweight and has high capacitance-voltage-temperature characteristics. It is suitable for operation in high-temperature environment and provides a superior dielectric and thermal performance. With its low effective series resistance, this type of capacitor is also suited for use in high-frequency circuits. Thanks to its long life and reliability, the M39003/01-5018 is a great choice for a wide variety of applications.
