Ceramic capacitors

Ceramic capacitors uses ceramic material as dielectric. Ceramic is used for its ability to permit electrostatic attraction and repulsion to take place across it. It makes an excellent dielectric because it is a poor conductor of electricity and makes an effective supporter of electrostatic fields.

The capacitors are manufactured using a tape-casting process wherein thin layers of conductive electrodes are separated by the dielectric layer. A kind of multilayer is formed to create a capacitor with a very large surface area in a very compact size.

Tecate Group ceramic capacitors

The Tecate Group uses a number of ceramic materials and compositions in their capacitors, including ceramic COG (NPO), ceramic X5R and ceramic Y5V.

COG is a dielectric with stable electrical properties across voltage, frequency and time. COG dielectric capacitors are suitable for circuits that require low loss in timing and tuning applications and offers the best capacitance precision.

The combination of nickel electrodes and the ability to cast very thin layers using X5R as dielectric material allowed the capacitance range of the capacitors to exceed more than 100 µF in a 1812 package.

The Y5V dielectric is a class III dielectric that exhibits a maximum capacitance change of +22%, -82% over an operating temperature range of +30 °C up to + 85 °C.

Tecate Group ceramic capacitors are available from very small sizes up to large configurations that have multiple agency certifications and can be used in safety-sensitive applications. We offer the following capacitor types: Radial capacitors, axial capacitors, surface mount capacitors and disc capacitors.
