Tantalum capacitors are electrical components used in the field of electronic engineering, acting as devices which store energy or act as filters for signal conditioning on electronic circuits. Tantalum capacitors offer a series of important advantages, such as improved reliability, smaller size, high stability of parameters and wide temperature range, compared to its aluminum or ceramic capacitors counterpart.

The M39003/01-3092H is a non-solid electrolyte-type type C30 tantalum capacitor, with axial lead form diameter of 3.5mm, and a case size of D4.55 millimeters. This type of capacitor is commonly used for decoupling, smoothing, and filtering, to provide aid in achieving reliable circuits.

In order to understand how the M39003/01-3092H functions, it is important to know the basic principles of how any capacitor works. It consists of two (or sometimes three) electrical conductors which are separated by a dielectric material, its role being precisely to store electrical energy.

Normally, a capacitor works by letting an electric current to pass from one conductor to the other. Whenever a voltage is applied between the two conductors, the electric field resulting from that action induces an electric dipole in the dielectric material. As a result, a charges separation is produced between the conductors, and even when the applied voltage is removed, the charges remain. This is the basic working principle of any capacitor, which in the case of the M39003/01-3092H is affected by the particular properties of the type C30 tantalum dielectric material.

The M39003/01-3092H is part of the 2nd generation of modern MnO2-tantalum capacitors, with important improvements in terms of reliability, voltage stabilizing ability and smaller size.

The M39003/01-3092H comes equipped with a Capacitance measuring between 0.1 to 0.47µF, a voltage of between 10V to 20V and a maximum working temperature of 85ºC. Other parameters include an ESR of 1.5Ω or less, at 100kHz and 1V, and a Z (-25ºC-+85ºC) of 8Ω or less.

In terms of applications, the M39003/01-3092H is used mainly as decoupling, smoothing and filtering capacitor, in reasonably current-intense supply lines, such as digital circuits, gate drive circuits, and LCD power supplies. Being significantly more reliable than other types of capacitors, it can reduce the ripple current in the supply line, minimizing the chances of malfunctioning in the circuit.

In conclusion, the M39003/01-3092H is a modern type C30 tantalum capacitor, which offers a range of advantages compared to other types of capacitors, such as improved reliability, small size, high stability of parameters and wide temperature range. Its main application fields are related to smoothing and decoupling of power supplies lines, but it can also be used as a filter for signal conditioning.
