Tantalum Capacitors: CWR26HH106KBFA\PR Application Field and Working Principle

Tantalum capacitors are electronic components that use tantalum for their anodes and instead of electrolyte, they use paper, plastic film, or liquid electrolyte for their dielectric layer. This type of capacitor has many advantages such as high capacitance density, low leakage current, high reliability, and low ESL and ESR values. Because of these advantages, tantalum capacitors are used in a wide range of consumer and industrial applications such as DC/DC conversion, medical equipment, computers, communications, digital circuits, and automotive electronics.

CWR26HH106KBFA\PR is a high-temperature, ultrasonic-welded tantalum capacitor. It is designed for audio, power supply, and general-purpose circuit applications and provides a high level of reliability and performance. The capacitor is a molded-case type with 105°C operating temperature, ± 20% tolerance, 8 V minimum rated voltage, 10 µF capacitance, and 18 mΩ maximum ESR.

CWR26HH106KBFA\PR Working Principle

The working principle of a tantalum capacitor is based on the effect of the dielectric material\'s electrical conductivity. When electric energy is applied to a device, charges of opposite polarity begin to accumulate at the two active surfaces of the dielectric material (anode and cathode). This process forms what is known as a capacitor. When the voltage reaches the breakdown voltage of the material, electrical energy is discharged and the capacitor is discharged.

In the case of CWR26HH106KBFA\PR, the anode is made of a solid tantalum metal that is electroplated with an oxide coating. This oxide coating acts as the dielectric layer, allowing the capacitor to store electric charge. The cathode is usually made of an electrolyte or other material that has a low voltage tolerance. The capacitor is then sealed with a plastic cover to protect it from the environment.

CWR26HH106KBFA\PR Application Field

CWR26HH106KBFA\PR is designed for use in applications that require high temperatures and high reliability such as power supplies, audio circuits, industrial controls, and automotive electronics. Its high capacitance density allows it to store large amounts of energy in a small form, enabling it to power circuits that require large amounts of energy but must remain compact. Its low ESR and ESL values translate into improved power supply design and system efficiency. The capacitor\'s long-term reliability also means it can withstand long-term stress with minimal degradation of its characteristics.

CWR26HH106KBFA\PR is also designed for use in medical equipment, high speed switches, high speed clocks, high current supplies, and automotive application. It is well-suited for use in high temperature environments because of its excellent thermal stability. The capacitor is also RoHS compliant, making it a viable option for use in lead-free designs.

Conclusion

Tantalum capacitors, such as CWR26HH106KBFA\PR, are widely used in a variety of consumer and industrial applications. They offer a high capacitance density, low leakage current, and excellent reliability. The capacitor is designed for use in high temperature applications and is also RoHS compliant, making it suitable for lead-free designs. CWR26HH106KBFA\PR is also well-suited for applications such as audio, power supplies, industrial controls, and automotive electronics.
