• Miniaturized MLCC, with top-level capacitance 22μF (2012 specification) and 47μF (3216 specification), suitable for smoothing and decoupling
• Realize a space-saving design and reduce the number of components
• Comply with AEC-Q200 standard

TDK Corporation (TSE: 6762) has developed a new product of CGA series multilayer ceramic chip capacitors (MLCC) suitable for automotive applications, realizing world-class capacitors^*, The 2012 specification (2.0 x 1.25 x 1.25 mm) capacitor is 22μF, and the 3216 specification (3.2 x 1.6 x 1.6 mm) capacitor is 47μF. The product has been mass-produced in September 2020.

In terms of improving safety, advanced driver assistance systems (ADAS) are becoming more and more important. At the same time, more and more functions to support autonomous driving have also been established. Therefore, ICs that control these characteristics are constantly providing more functions, and more and more smooth decoupling MLCCs are used to suppress noise. From the perspective of space-saving substrate design, the demand for miniaturized, high-capacitance MLCCs will continue to increase.

Compared with our traditional products, the new product has a smaller size and higher capacitance, which can reduce the number of MLCC components and realize a space-saving design. In the future, TDK will continue to expand its product range to provide services for the growing range of automotive applications.

Glossary

• AEC-Q200: Automotive Passive Components Standard of the Automotive Electronics Council
• Smoothing: by charging and discharging high-capacitance capacitors, suppress and smooth the fluctuation of the pulsating voltage in the rectified current
• Decoupling: By inserting a capacitor between the power line and the ground, and by temporarily supplying current when the electrical load changes suddenly, suppress the voltage fluctuation of the IC power line
• ADAS: Advanced Driver Assistance System

main application

• Smoothing and decoupling of electronic control unit (ECU) power lines in automotive applications

Main features and advantages

• The world's highest-grade capacitors (22μF for 2012 specifications, 47μF for 3216 specifications)
• Reduce the size, use high capacitance to reduce the number of components, and adopt a space saving design
