On April 17, TDK Corporation developed the industry's first soft-terminal multilayer ceramic chip capacitor with low ESR. This new CN series has terminal electrodes with a conductive resin layer to provide high mechanical strength and prevent substrate warpage. At the same time, the new laminated ceramic
Chip capacitors have a low ESR comparable to conventional products. The CN series has a capacitance value of 2.2 μF to 22 μF and a voltage rating of 16 V to 100 V. Based on X7R dielectric materials, commercial grades and automotive grades of the new multilayer ceramic chip capacitors are available. The latter has
It is certified by AEC-Q200, and the former will begin mass production and sales from April 2018.
Multilayer ceramic chip capacitors with soft terminals are able to withstand the stress generated by substrate warpage and are an effective way to prevent short circuits in battery circuits. The traditional design is to coat the electrode with resin, but this will result in higher ESR and loss. TDK only where the terminal electrode is in contact with the PCB
A conductive resin layer is applied to achieve a lower ESR. The new CN series has lower terminal electrode resistance, so these multilayer ceramic chip capacitors are suitable for battery circuits in automotive and industrial robot applications, helping to improve system reliability. This type of capacitor can also be used in cars
ECU, advanced driver assistance system (ADAS) and automatic driving system. TDK offers a broad portfolio of laminated ceramic chip capacitors for a wide range of applications. In the future, TDK will continue to pay special attention to the opening of automotive grade laminated ceramic chip capacitors with technological advantages.
