Introduction

Tantalum capacitors are electronic components that store and release electrical energy. They are also known as electrolytic capacitors. These capacitors use a tantalum molybdenum oxide as the dielectric material for its construction. They are widely used in various applications to provide efficient electrical energy storage. The 299D105X0035AB6 capacitors belong to the family of tantalum capacitors.

These capacitors are also used in switching power supplies, computers, high-density electronic circuit applications, anode side circuit of batteries, etc.

Working Principle of 299D105X0035AB6 Tantalum Capacitors

Tantalum capacitors are constructed with a tantalum molybdenum oxide dielectric material. This dielectric material consists of a layer of anode oxide which is formed in a process called “anodization”. The anode oxide layer provides an electrical insulation between the anode and the cathode. The present of anodic oxide also helps in increasing the capacitance of the capacitor. The charge and discharge behavior of the capacitor is controlled by the anode oxide layer. When voltage is applied across the electrodes, the physical movement of electrons occurs in the region between the anode and the cathode. Due to this, a reverse dielectric polarization is formed in the anodic oxide layer which allow it to store charge. When the voltage is removed, the stored charge starts discharging through another component connected in series with the capacitor. The discharge process is regulated by the dielectric material which has low capacitance loss. In addition to that, the total capacitance of the capacitor is increased when it is operating at higher temperatures.

Conclusion

The 299D105X0035AB6 tantalum capacitors are mainly used in automotive and aerospace applications due to its extended temperature range and long operational life. Its construction uses a tantalum molybdenum oxide dielectric material which provides an electrical insulation between the anode and the cathode. The physical movement of electrons occurs in the region between the anode and the cathode when voltage is applied across the electrodes which allow it to store charge. The dielectric material also helps in maintaining the total capacitance of the capacitor when it is operating at higher temperatures.
