- New 100 V product for automotive applications with 10 μF capacitance in 3225 case size (achieving large capacitance)
- Contributing to the reduction of component count and the miniaturization of sets
- Qualified based on AEC-Q200
April 14, 2025
TDK Corporation (TSE: 6762) has expanded its CGA series for automotive multilayer ceramic capacitors (MLCCs) to 10 µF at 100 V in 3225 size (3.2 x 2.5 x 2.5 mm – L x W x H), with X7R characteristics (Class Ⅱ dielectric). This is the industry’s highest capacitance* for a 100-V rated product in 3225 size and this temperature characteristic. Mass production of the product series began in April 2025.
While power consumption has increased and high-current systems have become more widespread in recent years with the increasing sophistication of ECUs, there is also demand for lighter vehicles (with lighter wiring harnesses), and the use of 48 V battery systems is becoming increasingly widespread. With this, there has been an increasing demand for high-capacity 100-V products, such as smoothing and decoupling capacitors used in power lines.
CGA series 100-V products achieve twice the capacity of conventional products of the same size thanks to optimized material selection and product design. This new product makes it possible to halve the number of MLCCs used and the mounting area, contributing to the reduction of component count and miniaturization of sets. TDK will further expand its lineup to meet the needs of customers.

Glossary
- Smoothing: Charging and discharging of high-capacity capacitors keep down the voltage fluctuations of pulse
flows in rectified currents, making them smoother
- Decoupling: Capacitors are inserted between IC power line and the ground to keep down the power line’s
voltage fluctuations by temporarily supplying a current when the load changes drastically
- AEC-Q200: Automotive Electronics Council. The standards for passive components for automobiles
Main applications
- Smoothing and decoupling of the power lines for various kinds of 48V products for automobiles
Main features and benefits
- Reduced component count and miniaturization of sets because the product offers a high capacitance of 10μF in 3225 size
- High reliability qualified based on AEC-Q200
