Tantalum capacitors are widely used in many electronic applications due to its high capacitance, low leakage, and low ESR. The M39003/01-8294 is a classic example of a tantalum capacitor, boasting excellent performance when used in various devices.

This device is a sort of axial lead capacitor with a long-life termination, also known as a hermetically sealed capacitor. It has a voltage range of from 16 to 450 volts, making it suitable for a wide range of applications.

The capacitance of the M39003/01-8294 is determined by the unit measured, the number of capacitors wound and what type of dielectric material is used for the fabrication. Generally, it has a capacitance ranging from 10 µF to 200 µF, and the package size varies from 2.8 mm to 7.9 mm.

When placed in a PCB, the M39003/01-8294 is designed for a maximum current limit of 1,000 mA as it is limited in size. This limitation, however, can be overcome by link connections between the capacitor and the PCB.

The M39003/01-8294 also features high temperature stability and a low leakage current. Its capacitance value changes very minimally (less than 10%) over a wide temperature range, making it a reliable component for high temperature applications. The device also exhibits high insulation resistance, a maximum of 1000 Gigohms at ambient temperature.

The M39003/01-8294 is ideally suited for DC-DC converter, point-of-load converters, buck or boost converters, and power supplies applications. It is also suitable for other applications like amplifiers, precision amplifiers, sample-and-hold amplifiers, and low-power audio amplifiers. It is also used in digital logic starting from programmable logic controllers (PLC) to digital signal processors (DSP), fax machines, digital cameras, and scanners.

The working principle of the M39003/01-8294 is quite simple. It is composed of two sheets of anode material (tantalum) separated by a dielectric. When two terminals of the device are connected to a power supply, electrical charges accumulate on the electrodes. This creates a capacitance between the two electrodes, also known as a capacitor. When voltage is applied to the terminals, electric charge accumulates on one of the electrodes, allowing for a current flow and creating an electric field. The current flow continues until the voltage is equalized between the two terminals, resulting in a steady state situation.

The M39003/01-8294 offers a wide range of advantages, enabling it to perform in a multitude of applications. Its axial lead package offers an excellent and reliable performance, while its high temperature stability and low leakage current make it suitable for high temperature applications. Furthermore, its high insulation resistance ensures that it can be used in applications requiring high insulation.
