Capacitors are one of the three major electronic passive components, which can hold charges and store energy. They are an indispensable basic component in electronic circuits and an important component of electronic products.
Ceramic capacitors are made of ceramics with high dielectric constant as the dielectric, and silver is plated on the ceramics by the sintering method as electrodes. There are many varieties of ceramic capacitors, and the dimensions are also very different. Ceramic capacitors have the advantages of large specific capacitance, good moisture resistance, small dielectric loss, and the temperature coefficient of capacitance can be selected in a wide range, and are widely used in electronic circuits. Many electronic products require ceramic capacitors, and the market demand for ceramic capacitors is gradually increasing. Many companies purchase ceramic capacitors in large quantities.
However, how should people who are not familiar with ceramic capacitors buy ceramic capacitors? Look at these tips when buying ceramic capacitors.
1. Look at the brand and manufacturer of ceramic capacitors
When choosing a ceramic capacitor, you must choose a capacitor manufacturer that has its own brand, production qualification and production base. Branded capacitor manufacturers are much better than non-branded in terms of quality and after-sales service. You also need to shop around to select cost-effective and suitable capacitor manufacturers.
2. Confirm the use of ceramic capacitors
Choose the appropriate ceramic capacitor according to the occasion of use. For example, class I ceramic capacitors' loss is small, temperature stability is good, and capacitance does not change with the temperature change, thus they are suitable for high-frequency resonant circuits. Class II ceramic capacitors have low cost and small size, and are suitable for low-frequency coupling circuits, bypass circuits, and filter circuits.
3. Look at the different dielectric of ceramic capacitors
The role and use of ceramic capacitors of different dielectric are also different. Under the same specifications, due to the different filling dielectric, the capacitance of ceramic capacitors is also different, and the dielectric loss, capacitance stability, and applicable occasions of ceramic capacitors are also different. Commonly used dielectrics for ceramic capacitors include NPO/COG, X7R, Z5U, Y5V, etc.
If you don't know how to choose a ceramic capacitor, you can tell your needs to a trustworthy capacitor manufacturer. A reliable capacitor manufacturer will choose a suitable ceramic capacitor for you according to your needs.
