MLCCs in 3225 size for automotive and commercial applications

TDK Corporation has expanded its CGA series for automotive and C series for commercial MLCCs to 10 nF at 1,250 V in 3225 size (3.2 x 2.5 x 2.5 mm – L x W x H), with C0G characteristics (Class I dielectric). This is the industry's highest capacitance for a 1,250V rated product in 3225 size and this temperature characteristic.

Circuits using SiC MOSFETs, which can withstand high temperatures and high voltages, are being adopted, and more and more circuits are becoming higher voltage and higher current to decrease the charging time of EVs. With this, the demand for high-voltage resistance for resonant and snubber capacitors grows.

C0G characteristic products alter their capacitance only slightly over temperature and voltage, making them excellent for such applications. These MLCCs are high voltage resistant because their product and process design were optimised. This makes them compatible with high-voltage circuits and makes it feasible to reduce the number of MLCCs mounted in series, contributing to space-saving designs. Furthermore, compared to the company's previous products, it can lower the heat generated and, therefore, contributes to preventing excessive heat in the applications.
