Tantalum Capacitors

Tantalum capacitors, also known as taipacitors, are tiny, low-profile capacitors used to store electrical potential energy. They are often used in communication equipment, medical equipment, and military applications due to their size, low cost, high-efficiency, and high-temperature operation. One of the most popular types of tantalum capacitors is the CWR26HH107MBHC/HR.

The CWR26HH107MBHC/HR is a type of surface-mount, non-polarized, electrolytic capacitor. The construction of the capacitor is unique, as the capacitor uses a solid tantalum base and tantalum oxide as the semiconductor material and the dielectric material. This combination results in an extremely efficient and reliable capacitor.

The CWR26HH107MBHC/HR has a maximum operating temperature of 85°C, a capacitance of 107mF, and has a wide range of working voltages from 4.2 to 10V. It also has an extremely high insulation resistance, which ranges from 1000MΩ to 2000MΩ. The capacitor also features RC-type stability, and has a very long service life of 20000 hours.

In terms of applications, the CWR26HH107MBHC/HR capacitor is used in a variety of applications, including low-power digital and analog circuit designs, battery-powered circuits, RC time constant circuits, and noise filters. In particular, it is an ideal choice for applications that require reliable high-temperature operation in a small package. The capacitance can also be optimized for applications that require a high capacitance.

Working Principle

Tantalum capacitors use a solid dielectric of tantalum oxide within the capacitor. The oxide is formed by the reaction of the anode metal (usually tantalum) to oxygen, forming a tantalum dioxide layer on the surface of the anode metal. This dielectric has a high dielectric constant which results in an increased capacitance for a given volume.

The capacitance of a tantalum capacitor depends on the area of the dielectric layer, the thickness of the dielectric layer, and the applied voltage. The applied voltage determines the dielectric constant of the layer, and thus the capacitance. The capacitance of a tantalum capacitor increases when the applied voltage is increased.

The structure of the capacitor also determines its working principle. The solid electrolytic capacitor consists of two metal plates (anode and cathode). When a voltage is applied to the metal plates, current flow occurs through the electrolyte, and electrons are drawn through the electrolyte to the anode. The electrons flow through the dielectric layer, and the current flow is blocked when the voltage applied to the plates is equal to or greater than the dielectric constant of the dielectric.

In summary, the CWR26HH107MBHC/HR capacitors are low-profile, efficient capacitors which are suitable for a variety of applications. Their construction is unique, as they feature a solid tantalum base and tantalum oxide as the semiconductor and dielectric materials. The CWR26HH107MBHC/HR has a maximum operating temperature of 85°C and offers high insulation resistance, along with RC-type stability and long service life.
