TDK Multilayer Ceramic Chip Capacitors
Small chip capacitors are widely used in telecommunications,PC, automatic and control systems
TDK multilayer ceramic capacitors are represented in a few series of chip capacitors.
Features
- They suit for substitution of tantalum, some types of film and aluminum capacitors
- They have nickel electrodes providing optimal range between price and quality.
- They can be applied in different fields:from mobile phones to automobile industry.
The structure
Multilayer ceramic chip capacitor consists of ceramic dielectric and metallized electrodes. CaTiO3 and BaTiO3 are used as dielectrics. High capacity value is being achieved due to increasing of electrodes number and decreasing of dielectric thickness.
Monolithic structure provides mechanical strength and reliability.
Due to high accuracy of capacitors sizes it's possible to apply them in automation systems when arranging components on a circuit board.
