MLCCs claim to be first soft-termination versions
Multi-layer ceramic chip capacitors (MLCCs) from TDK are believed to be the industry’s first soft-termination MLCCs with low ESR. The CN series features terminal electrodes with a conductive resin layer that provides high mechanical robustness to protect against board flex.
The CN MLCCs offer a low ESR that is comparable to that of conventional MLCCs, says TDK. The CN series offers capacitance values ranging from 2.2 to 22µF and rated voltages from 16 to 100V. Based on X7R dielectric material, TDK offers commercial grade and automotive grade types of the MLCCs. The automotive grade MLCCs are qualified to AEC-Q200.
Soft-termination MLCCs are able to withstand the stress from board flex, and are an effective way to prevent short circuits when used in battery lines. Conventional designs that coat the electrodes completely with resin, lead to higher ESR and losses. TDK claims that it has achieved the low terminal resistance values by applying the conductive resin layer only where the terminal electrode comes into contact with the PCB. The low resistance of the terminal electrodes of the CN series make these MLCCs suitable for battery lines in automotive and industrial robot applications, where they help to improve system reliability. The capacitors can also be used in automotive engine control units (ECUs), advanced driver assistance systems (ADAS), and automated driving systems.
TDK offers a broad portfolio of MLCCs for a range of applications.
