Tantalum Capacitors

This article will discuss the application field and working principle of CWR26HB106KBFC\HR. Tantalum capacitors are passive electronic components comprising of two conducting plates separated by an ionic conductor. The two plates are called anode and cathode and the media between the two is called electrolyte. These components convert electrical potential energy into stored energy through electrochemical reactions.

The “CWR” in the product designator CWR26HB106KBFC\HR denotes its wet Tantalum capacitor. “CWR” stands for “Capacitance-Wet-Ruggedized” indicating that it is an electrolytic capacitor. The 26 in its designator denotes its case size, 26mmx26mm, with a height of 16.1mm and a 113g weight.

The designator “HB” denotes that this is a polarized device, with the “H” designator indicating a “heat sink” package, meaning that the device has its own housing which acts as a cooling mechanism and shields it from environmental elements. The 106 in the designator denotes the capacitance, 100uF, which is the typical charge storing capacity for the device. The “K” in the designator “KFC\HR” denotes the voltage, 10V, for which the device is designed.

Tantalum capacitors can operate within a temperature range of -55oC to +125oC. Their operating life is generally limited to 500 to 1000 hours at +85oC but may vary depending on their design. These capacitors have relatively high dissipation factors and relatively low current handling capacities, making them suitable for use in relatively low power applications. The high dielectric strength of Tantalum capacitors allows higher reverse breakdown voltages, preventing overvoltage damages.

The working principle of the CWR26HB106KBFC\HR capacitor is based on the flow of current through the device in order to store and release electrical charge. The device creates a high impedance bridge between two conductors, with the anode being positively charged and the cathode being negatively charged. When a voltage differential is applied across the device, a reverse bias current, called reverse leakage current, will flow from the anode to the cathode, charging the anode until its charge reaches the cathode. When the external voltage is removed, the stored charge dissipates, releasing the energy stored.

The CWR26HB106KBFC\HR Tantalum capacitor is used in many consumer electronics applications as well as in industrial and scientific applications. These include RF communications, video and audio equipment, medical equipment, automotive electronics, aircraft and spacecraft systems. It is used in high-frequency applications, high current applications that require low energy dissipation, and for similar applications where capacitance ratios are important.

Tantalum capacitors have good DC stability, making them ideal for general purpose requirements and for use in signal coupling networks. They can be used in high reliability applications in aircraft and satellite communication equipment. Their low voltage and low power characteristics make them ideal for battery powered applications as well.

In conclusion, the CWR26HB106KBFC\HR Tantalum capacitor is a versatile device used for a wide variety of applications. It has excellent DC stability and low power characteristics, making it an ideal choice for a variety of applications in consumer electronics, industrial, and scientific applications. In addition, its low cost and wide range of voltage and capacitance ratings make it a popular choice amongst engineers.
