It has an operating capacitance range of 10 to 330 μF, a derating factor of -0.8% per °C, and a dissipation factor of 3.8. In addition, it features a tolerance of ± 20%, low ESR and ESL, high reliability, and low leakage current.

Application Fields

The CWR26HB107JCHA\HR capacitor is designed for use in a variety of demanding applications including military, avionics, space, automotive, and other high-reliability applications. It is exceptionally suitable for use in DC-DC converters, SMPS circuits, RF and traditional oscillators, and pulse circuits. Furthermore, because of its low ESR and ESL, it is ideal for use with high-frequency signals, high-speed pulses, and power supplies.

Working Principle

Tantalum capacitors work in a similar way to other types of capacitors. When current is passed through the capacitor, it forms an electrical field between two conducting surfaces, storing energy in the form of an electric field. As this electric field is increased, the capacitor can store larger amounts of energy. Tantalum capacitors are different from other types of capacitors because they use a tantalum metal plate as one of the conducting surfaces. This increases the capacitance of the device.

The tantalum plate is surrounded by an electrolyte, such as manganese dioxide. This electrolyte serves two purposes: it allows ions to enter and leave the plate, allowing the capacitor to store energy more efficiently, and it serves as a dielectric, increasing the voltage the capacitor is capable of handling. Combined, these two materials allow the capacitor to store an impressive amount of energy.

Conclusion

The CWR26HB107JCHA\HR is a high-quality tantalum capacitor designed for use in demanding industrial applications. It is a reliable, high-performance capacitor with a rating up to 6.3 VDC and an operating temperature range of -55 to +125°C.
