Tantalum capacitors, like any other semiconductor device, are widely used in a range of electrical applications from computers and cell phones to aviation, medical, and military equipment. The M39003/01–6386/TR is a popular series of tantalum capacitors manufactured by Vishay Intertechnology and distributed globally. This article will discuss the background of the device, its application field and the basic working principle of the tantalum capacitor.

Introduction to M39003/01–6386/TR Tantalum Capacitors

M39003/01–6386/TR is a series of metal case commercial grade, conformally coated (as described by MIL-P-50884), polarized (by means of a cathode mark and a concave notch in its body), radial leaded and hermetically sealed (with epoxy resin) tantalum capacitors manufactured by Vishay Intertechnology. With a voltage rating of 16 VDC and capacitance ranging from 1μF to 22μF, this series of tantalum capacitors feature a high-temperature stability, a very low ESR, and are insulated with a conformal coating and moisture-resistant materials for extended life and reliability.

Application Fields of M39003/01–6386/TR Tantalum Capacitors

The M39003/01–6386/TR series of tantalum capacitors is suitable for a variety of applications because of its robust design, long life and high reliability in a wide range of environmental conditions. Common application fields include consumer electronics, computer power supplies, industrial equipment and communication systems. The robust nature of these series make them capable of being used in sensitive environments whether it is in space, military and medical applications or harsh weather conditions such as in automotive applications.

Tantalum capacitors use their inherent properties to store electrical energy. They are ideal for decoupling and filtering electrical pathways as they exhibit low impedance at their rated frequencies and are very reliable. They are also able to keep their capacitance values stable even with a changing temperature, making them highly suitable for the harsh climates which may be encountered in certain applications.

Working Principle of M39003/01–6386/TR Tantalum Capacitors

The working principle of a tantalum capacitor is based on the same principles as other types of capacitors. The capacitor is made up of two metal layers separated by a dielectric material. Typically the layers are made of anode and cathode materials which in the case of tantalum capacitors are a mixture of tantalum powder and a manganese dioxide paste. The dielectric material in this case is an oxide layer that forms when the capacitor is subjected to a voltage.

When an AC or DC source is applied, a drop in voltage is observed across the capacitor. The dielectric material provides an electrical insulation between the plates and allows the capacitor to store charge and electrical energy. The capacitance value of the capacitor is determined by the area of the plates and the distance between them. The size and form of the capacitor determines its maximum rated voltage.

Conclusion

The M39003/01–6386/TR is a relatively simple series of tantalum capacitors designed for general use. They exhibit long life, robust designs and reliable performance in a variety of applications. Their working principle is also relatively straightforward to understand, which makes them suitable for beginner users.
