It is highly suited for use in voltage regulators, DC-DC converter power supplies, switching power supplies, and Audio and Video equipment. It can also be used in Computers, Telecommunications, Marine and Automotive applications.

Working Principle of the 1879065-9 Tantalum Capacitor

Tantalum capacitors are ideal for many applications because of their ability to operate over a wide temperature range and provide high capacitance in a small package. The 1879065-9 tantalum capacitor utilizes a piece of tantalum metal as the anode. This anode is coated with a dielectric insulating layer and is then sealed with special epoxy in the case. An electrolyte is used as the cathode.When a potential difference of equal magnitude and opposite polarity is applied across the two terminals of the capacitor, the dielectric barrier is partially broken down by the field effect created by the potential difference. This phenomenon, known as "electrolytic polarization," causes electrons to flow from the anode to the cathode, allowing current to flow through the capacitor.The amount of charge stored within the capacitor is dependent on the dielectric barrier strength, and is a function of the thickness of the insulating layer. As capacitors operating at higher voltage levels require thicker insulation layers, the 1879065-9 capacitor is able to handle up to 50 volts.

Conclusion

The 1879065-9 is a type of tantalum capacitor that is useful for a variety of power application fields and has a wide operational temperature range. It has a capacitance value between 10µF and 47µF and can handle up to 3A of current. Its working principle is based on the dielectric barrier strength and electrolyte polarization. The 1879065-9 tantalum capacitor is thus an ideal choice for many power applications.
