Tantalum capacitors, also known as the tantalum electrolytic capacitors, are widely used for a variety of tasks in the electronics industry. M39003/01-5697/TR application fields and working principle are related to the properties of this type of capacitor.

Tantalum capacitors are composed of a tantalum metal oxide anode, a thin oxide film dielectric layer, and a conductive cathode foil, as well as being packaged in an epoxy/polypropylene package. The anode is the positive terminal, and the cathode is the negative terminal.  The voltage rating of a tantalum capacitor is determined by the voltage rating of the dielectric oxide film, and the current rating by the residue capacitance of the device. Due to the excellent properties of the tantalum oxide films, these components offer excellent electrical characteristics in terms of resistance to electrical shocks, noise, and temperature.

The most common of the M39003/01-5697/TR application fields are related to the stable output capacitance across wide temperature ranges in order to prevent short circuits in critical circuits. The increased stability of the output capacitance over an operating temperature range is why many systems have chosen to use these capacitors. This type of capacitor is also very resistant to the effects of higher temperature, making it ideal for use in high temperature areas.

In terms of working principle, a tantalum capacitor works by electrochemically deposition of an anode oxide film on the anodic material. When a voltage is applied across the capacitor, the oxide film becomes an insulating layer, which serves as the dielectric oxide, and the output capacitance is determined by the thickness of the dielectric film. With a greater thickness, the output capacitance of the capacitor increases.

When it comes to applications, the M39003/01-5697/TR is often used in power supplies or other applications requiring a very stable output capacitance. This type of capacitor generally has a lower ESR and higher current rating compared to other types of capacitors, making them more suitable for use in high current applications.  These capacitors are also more resistant to high temperature applications, making them suitable for high temperature circuit board layouts.

In summary, the M39003/01-5697/TR application fields and working principle are associated with the properties of tantalum capacitors. These capacitors provide increased stability of output capacitance over a wide temperature range, and are ideal for use in high temperature applications where other types of capacitors may not be suitable. The output capacitance of a tantalum capacitor is determined by the thickness of the dielectric oxide film, and the increased stability and higher current rating of these devices make them an ideal choice for use in power supplies or other critical applications that require higher stability.
