  • What is a ceramic capacitor?

  • A ceramic capacitor is a capacitor which uses a ceramic material as the dielectric. The two most common types are multi-layer ceramic capacitors and ceramic disc capacitors. There are two classes of ceramic capacitors available today: class 1 and class 2.

  • What are the types of capacitors used in electronic devices?

  • Ceramic Disc Capacitors 鈥?These are often used as safety capacitors in electromagnetic interference suppression applications. Multi-layered Ceramic Capacitors 鈥?Ceramic capacitors with multilayer style (MLCC) are widely used and produced capacitors applied in the electronic equipment.

  • Why do we use ceramic capacitors instead of mica?

  • In circuits where a small size of capacitor is required Ceramic capacitors comes into picture. These where intially developed in German as replacement for mica. Before 1920鈥檚 due to insulating properties of mica it was used as a dielectric material in a capacitor.

  • What is the difference between MLCC and ceramic capacitors?

  • MLCCs are the most produced capacitors with a quantity of approximately 1000 billion devices per year. They are made in SMD (surface-mounted) technology and are widely used due to their small size. Ceramic capacitors are usually made with very small capacitance values, typically between 1nF and 1F, although values up to 100F are possible.
