TDK expands automotive MLCC lineup with the industry's highest capacitance at 100V in 2012/3216 sizes

  • New 100V automotive types with 2.2μF in 2012 size and 4.7μF in 3216 size (achieving high capacitance)
  • Enabling space-saving designs and a reduction in number of components
  • Qualified based on AEC-Q200

TDK Corporation (TSE: 6762) has expanded its CGA series of multilayer ceramic capacitors (MLCCs) to 2.2μF in 2012 size (2.0 x 1.25 x 1.25mm – L x W x H) and 4.7μF in 3216 size (3.2 x 1.6 x 1.6 mm – L x W x H), with the industry's highest capacitance*, as 100V products for automotive applications. Mass production of the product series began this month, March 2024.

Many automotive manufacturers are adopting a 48V electrical architecture for several reasons, including automotive fuel efficiency (power efficiency). This has increased the demand for miniaturized high-capacitance 100V products, which are useful for smoothing and decoupling in power lines.

Thanks to optimized product design, the 100V products of the CGA series achieve smaller size and higher capacitance. TDK will expand its lineup further to meet customers' needs.

Features & Applications

Main applications

  • Smoothing and decoupling of the power lines for various kinds of 48V products for automobiles

Main features and benefits

  • Higher capacitance of 2.2μF in 2012 size and 4.7μF in 3216 size enables space-saving designs and a reduction 
    in number of components
  •  High reliability qualified based on AEC-Q200 


  • Smoothing: Suppressing and minimizing voltage fluctuations of pulsating voltage in rectified current by charging and discharging high capacitance capacitors
  • Decoupling: Suppressing voltage fluctuations of IC power lines by inserting capacitors between the power line and the ground and by temporarily supplying current when the electrical load abruptly changes
  • AEC-Q200: Automotive Electronics Council standard for passive automotive components
