Tantalum capacitors are electronic components that store electrical energy as a static charge. They are especially valuable since they can release their charge very rapidly and are rated for high energy capacitance. The M39003/01-6120/TR is a series of tantalum capacitors designed by the Vishay Intertechnology company.

Design and Construction of the M39003/01-6120/TR

The M39003/01-6120/TR is a series of miniature molded tantalum capacitors. Constructed from an epoxy-coated metal casing, the M39003/01-6120/TR features a voltage range of up to 35V, a temperature range from -55°C to +205°C and an insulation resistance of up to 30,000 MΩ. The capacitance of the series ranges from 1μF to 470μF, with small capacitance variations depending on the voltage.

Working Principle

The working principle of the M39003/01-6120/TR is the same as any other type of capacitor. In a capacitor, two conductors (plates) are separated by an insulating material known as the dielectric. When a voltage source is applied, electrons of one of the conductors are attracted towards the opposite plate, while electrons of the other plate are repelled due to electrical polarization. This creates a charge imbalance between the two conductors, thus creating an electrical potential difference and storing energy in the form of an electrical field. When the voltage source is disconnected, the charge will remain on the capacitor’s conductors, and can be used to power other electronic components.

Application Field

Tantalum capacitors such as the M39003/01-6120/TR are used in applications that require high energy storage levels, such as for voltage smoothing, buffering, and power supply filtering. They are also used in high-frequency telecommunications, military, and automotive electronics, wherein the high voltage and temperature tolerances of the device are beneficial. Other common applications of the M39003/01-6120/TR and other tantalum capacitors include power-conditioning circuits, low-frequency waveform-shaping circuits, dead time control circuits, and timing circuits.

Advantages of the M39003/01-6120/TR
