Tantalum capacitors are a type of electrolytic capacitor that provides the highest level of capacitance per unit volume compared to all other circuit board capacitors.  Tantalum capacitors are often used in high frequency, high temperature, or high-voltage conditions, where they offer superior performance and lifetime compared to other types of capacitors.  They are often used in automotive, medical, and industrial applications, such as in the automotive, aerospace, consumer electronics, and telecommunications industries. 

Types of Tantalum Capacitors

Tantalum capacitors come in two main types: solid tantalum and wet tantalum.  Solid tantalum capacitors are made with a compressed powder form of the tantalum compound, which is housed in a sealed case and connected with one or more electrical connections.  Wet tantalum capacitors, on the other hand, are assembled using a wet tantalum capacitor slug, which is placed inside a sealed tube with an oxidizing atmosphere and connected with one or more electrical connections.  The slug is then surrounded by a dielectric, such as a plastic coating, that insulates the slug from its surroundings. 

CWR26HB107JHBZ

The CWR26HB107JHBZ is a wet tantalum capacitor, meaning it is assembled using a wet tantalum capacitor slug.  This capacitor has conducting anodes and a cathode made of a special alloy of Tantalum. The anodes are surrounded by a dielectric which consists of a solid-state coating of PTFE, or Polytetrafluoroethylene. The use of PTFE as a dielectric helps to provide insulation between the anodes and the cathode, thus allowing it to present a higher capacitance than a solid tantalum capacitor. The characteristic frequency of this capacitor is between 200kHz and 400kHz, making it ideal for high frequency applications. It is rated for a maximum capacitance of 105J, a maximum working voltage of 16V, and a maximum leak current of 40uA.

Applications of CWR26HB107JHBZ

The CWR26HB107JHBZ is mainly used in applications where high frequency and high temperature performance are needed, such as in automotive, medical, or industrial applications. It is also suitable for use in high frequency AC or DC circuits, as well as other high voltage or high temperature environments. This capacitor is also commonly used in high frequency signal filtering and low noise signal amplification. 

Working Principle of CWR26HB107JHBZ

The CWR26HB107JHBZ capacitor operates on the principle of storing electric potential energy in an electrostatic field generated between two conducting surfaces. When a reverse-biased voltage is applied to the capacitor’s anodes, an electrostatic field is generated between the anodes, which exerts a repulsive force on the electrons, causing them to be repelled away and thus stored in the capacitor. This stored electric energy can then be released when the capacitor is discharged.

Conclusion

Tantalum capacitors, specifically the CWR26HB107JHBZ, are a type of electrolytic capacitor that offers superior performance and lifetime compared to other types of capacitors. It is used in applications where high frequency and high temperature performance are needed, such as automotive, medical, or industrial applications. The operating principle of the CWR26HB107JHBZ is based on the principle of storing electric potential energy in an electrostatic field generated between two conducting surfaces.
