TDK Corporation 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.
Main applications
- Smoothing (Charging and discharging of high-capacity capacitors keep down the voltage fluctuations of pulse flows in rectified currents, making them smoother) and 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) 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
