Tantalum Capacitors

Tantalum capacitors are incredibly useful electronic components, due to their high capacitance and remarkable electrical properties. However, the wide variety of tantalum capacitors available on the market means that it can be difficult to find the one that best meets your needs. The CWR26HH336MBFA/TR is a particular type of tantalum capacitor, and this article will explore its various application fields and working principle.

What are Tantalum Capacitors?

Tantalum capacitors are a type of electrolytic capacitor which utilize a tantalum metal as an anode and an oxide as a dielectric medium. The metal-oxide interface offers superior capacitance in a very small space. This makes them ideal for a number of applications, such as low-power decoupling and time-dependent waveform filtering.

Applications of CWR26HH336MBFA/TR

While the CWR26HH336MBFA/TR has many of the same properties as other tantalum capacitors, its high capacitance and low ESR (equivalent series resistance) make it particularly useful for current filtering applications. As a result, it is often used as a bypass capacitor, helping to reduce electrical noise and filtering out AC signals. Additionally, because it is a “high temperature” capacitor, the CWR26HH336MBFA/TR is well suited for use in ICs, memory modules, microprocessors, and other high-power circuits that require the capacity to handle extreme temperatures.

Working Principle of CWR26HH336MBFA/TR

The CWR26HH336MBFA/TR uses a tantalum ring as its anode and an oxide layer as its dielectric. Two metallic leads create a link between the ring and the capacitor’s terminals. This design allows for a high capacitance value in a very small volume – many variants of the CWR26HH336MBFA/TR are available in packages measuring just 0.033” in length. This design also has a very low ESR compared to many other types of capacitors.

The CWR26HH336MBFA/TR is an electrolytic capacitor, meaning it stores energy by separating two metal surfaces of opposite polarity and creating an electric field. When a voltage is applied, positive ions build up at the anode, while negative ions attract to the cathode. This buildup of ions creates a charge at the capacitor’s terminals which can be used as a source of energy. The capacitance of the CWR26HH336MBFA/TR is thus determined by the amount of charge it can store per unit voltage.

Conclusion

Tantalum capacitors have a wide variety of applications, and the CWR26HH336MBFA/TR is a particularly useful variant due to its high capacitance and low ESR. This capacitor is ideal for applications where current filtering is important, such as in memory modules, microprocessors and ICs, and it is especially suitable for high-power circuits that require the capacity to handle extreme temperatures. Its design is such that it contains a large capacitance value in a very small volume, making it a highly efficient component.
