The capacitor is well-suited for operation over a wide frequency and temperature range, making it suitable for industrial and automotive applications.

Design and Structure

The CWR26HC226KCGB/PR is constructed from tantalum and is available with a range of capacitance values from 22µF to 560µF. The device has a low profile design, measuring only 14.7mm × 7.6mm × 5.3 mm. Its low ESR and ESL values make it suitable for high current, low voltage power applications. The capacitor’s performance is further enhanced by its low temperature coefficient and low leakage current.

Working Principle

Tantalum capacitors work on the same principle as other types of capacitors. A capacitor stores energy in an electric field that is created by charges of opposite polarity on two conducting plates separated by a dielectric. Current flowing through the capacitor creates a voltage across its plates, which is the basis for its use in a variety of electrical applications.In the case of tantalum capacitors, the dielectric material is a solid electrolyte which is made from an oxide powder and a tantalum metal anode. The electrolyte is applied to the anode and the structure of the capacitor is then formed by compressing the anode and electrolyte powder together into the shape of a capacitor. It is this solid electrolyte that gives the capacitor its characteristics of low leakage current and high capacitance.

Conclusion

The CWR26HC226KCGB/PR is a high-capacity, low-profile tantalum capacitor that is well-suited for use in a variety of power electronic applications. Its low profile design, low temperature coefficient, and low ESR and ESL values make it an ideal choice for high-governance, power-clamping, and power-limiting circuits. Additionally, its solid electrolyte construction gives it characteristics of low leakage current and high capacitance. The CWR26HC226KCGB/PR is a reliable and efficient choice for many power electronics applications.
