Tantalum capacitors are an advanced type of capacitor made from tantalum and manufactured as a wet electrolytic capacitor and a dry-jacketed solid capacitor. CWR26HB106MBFA\PR, a themoplastically molded, discrete solid tantalum capacitor, is one of the standard components used in many consumer electronic equipment.

Applications

The CWR26HB106MBFA\PR is a molded solid chip tantalum capacitor, which makes it suitable for consumer electronic applications because it is able to provide long-term reliability and performance in high temperature environments - typically up to 125°C. It is often used to create a direct-connect power supply, or as a heat sink to dampen voltage transients.

The capacitor is known for its ability to function at high frequencies, while also providing low ESR (Equivalent Series Resistance) over a range of conditions. This makes it particularly suitable for use in high-end consumer electronics, such as portable device chargers, battery-powered devices, and communication equipment. The capacitor offers superior protection against reverse voltage, which helps to greatly reduce system noise and improve system performance. Furthermore, the CWR26HB106MBFA\PR also features a wide operating temperature range and high capacitance per volume.

Working Principle

The working principle of CWR26HB106MBFA\PR relies on the same principles as other tantalum capacitors. In this type of capacitor, an electrode is created by metallizing two layers of tantalum metal with another metal, such as molybdenum or tungsten. A dielectric material, such as manganese dioxide, is then deposited between the two metallized layers and the capacitor is then sealed with a moisture-resistant solution, forming a wet tantalum electrolytic capacitor.

In a dry-jacketed solid capacitor, a rigid dielectric sheet, such as polypropylene, is sandwiched between the two metallized tantalum layers and is then hermetically sealed with an epoxy and silicone compound. This forms a structure more robust than a wet tantalum electrolytic capacitor and is less prone to leakages.

In both types of capacitor, the capacitor’s ability to store energy is dependent on the applied voltage and the size of the capacitor plates. When a voltage is applied to the capacitor, an electric field is created, inducing an electric flux across the dielectric material, resulting in charge accumulation on the electrode plates. This accumulated charge is what stores the energy in the capacitor.

In conclusion, CWR26HB106MBFA\PR is a type of extensively used tantalum capacitor in consumer electronics. Its applications include direct-connect power supply, heat sink dampening voltage transients and offering protection against reverse voltage. This capacitor works on the principle of electrode plates, dielectric material and creating an electric flux in the capacitor when a voltage is applied.
