Tantalum capacitors are widely used in modern electronics due to their relatively high dielectric constant, temperature characteristics and good electrical stability. CWR26HH107JCHB/PR are tantalum chip capacitors with better properties, compared with conventional electrolytic capacitors. This article will explain the application field and working principle of CWR26HH107JCHB/PR.

Application Field

CWR26HH107JCHB/PR are widely used in the fields of mobile phones, mid/low frequency wireless communication, portable music players, digital cameras, and electronic games. Other applications include high frequency transformers, electric scooters, solar cell power supplies, batteries, etc. Their high stability makes them ideal for high-powered boards, eliminating the risk of burning and damaging other components.

Working Principle

Tantalum capacitors generally consist of three parts - an anode, a dielectric material and a cathode. The anode of the CWR26HH107JCHB/PR is a precut tantalum foil, which is wrapped with a layer of dielectric material, usually an oxide film. The dielectric is made from tantalum pentoxide (Ta2O5). The cathode is usually made of conductive polymer layers. When the capacitor is in use, an electric field is formed between the anode and cathode. The electric field allows positive ions to move from the anode to the cathode. This creates a charge on the two electrodes. The dielectric material prevents the electrical current from flowing between them, thus storing the energy.

Tantalum capacitors have many advantages. They have high capacitance-to-volume ratios and are usually the smallest available of the electrolytic capacitors. They also generally have a very low ESR (Equivalent Series Resistance), as well as low leakage currents. In addition, they are temperature and voltage insensitive, which makes them ideal for applications where these factors must be carefully controlled.

Conclusion

CWR26HH107JCHB/PR are highly reliable tantalum chip capacitors which are widely used in many electronic applications. They have excellent electrical characteristics and have been used to maximize the power of high power boards. Their high capacitance-to-volume ratio is one of the advantages which make them the preferred choice in many applications. They also have very low ESR and leakage currents, making them suitable for applications where electricity and temperature must be tightly controlled.
