TDK Adds 100V Variation in Automotive MLCC Line

TDK Corporation has expanded its CGA Series of multilayer ceramic capacitors (MLCCs) to 2.2μF in 2012 size (2.0 × 1.25 × 1.25mm – L × W × T) and 4.7μF in 3216 size (3.2 × 1.6 × 1.6 mm – L × W × T), with the industry’s highest capacitance*, as 100V products for automotive applications. Mass production of the product series began in March 2024.

CGA Series high-capacitance MLCC

Generally, many automotive manufacturers are adopting a 48V electrical architecture for several reasons. Among them include automotive fuel efficiency (power efficiency). Accordingly, this has increased the demand for miniaturized high-capacitance 100V products, which are useful for smoothing and decoupling in power lines. Additionally, the new products are qualified based on AEC-Q200.

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


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
