Operating Temperature: The maximum operating temperature of the M39003/03-3022 capacitor is 85°C, making it suitable for most applications within a wide temperature range.

Rated Voltage: The M39003/03-3022 capacitor can be used at a DC rated voltage up to 35V, making it suitable for high-current applications.

Applications: The M39003/03-3022 capacitor can be used in a variety of applications, including power supplies, LED lighting, and amplifier circuits. Its miniature size and flexibility make it the ideal choice for designers who need a reliable high performance capacitor that can fit into tight spaces.

Working Principle: The M39003/03-3022 capacitor functions using the principle of electrolytic capacitance. When a voltage is applied between the anode and cathode, an electric field is created which causes ions to concentrate in the dielectric layer between them. This creates a positive charge on the anode and a negative charge on the cathode, forming an electric double layer which is responsible for storing electrical charge.

The dielectric layer of the capacitor is made of a tantalum oxide, which has a high dielectric constant. This means that for a given size and capacitance, the tantalum capacitor is much more energy dense than traditional ceramic or paper capacitors. The tantalum oxide also has a very low loss and good stability, making it a reliable choice for many applications.

The electrolyte used in the M39003/03-3022 capacitor is a type of conductive solution that facilitates the ion transport. This enables the capacitor to function even in high temperature environments without any issues.

The working principle of the M39003/03-3022 capacitor makes it an ideal choice for applications that require reliability and high performance in extreme conditions. Its ultra-small size and flexibility also make it suitable for use in a wide range of applications.
