Working Principle of M39003/03-2028/TR Tantalum Capacitor

Tantalum capacitors are a type of non-polarized electrolytic capacitors, which consist of an anode made from tantalum and a cathode made from oxide or nitride. The anode and cathode are separated by an electrolytic solution that acts as an electrical insulating and dielectric material. Once a voltage is applied across the terminals, a current flows through the device. This current causes an electric field to form in the dielectric material, which causes the electrons in the cathode to be attracted to the anode, resulting in a buildup of charge. Because the charges can be both positive and negative, the tantalum capacitors offer a high capacitance value.

The M39003/03-2028/TR tantalum capacitor is constructed with the same principles as other tantalum capacitors, but is specifically designed for high temperature and voltage applications. The case of the capacitor is designed to dissipate any excess heat, ensuring that the temperature inside the device does not exceed its specified limit. Additionally, the plates are constructed from tantalum, an element known for its high resistance to corrosion and aging. This ensures consistent performance over time.

Conclusion

The M39003/03-2028/TR tantalum capacitor is a popular choice for applications that require high temperature and voltage ratings. Its unique features, such as wide operating temperature range and excellent characteristics, make it the ideal solution for many board-level applications.
