TDK releases new miniaturized, common-mode filters for high-temperature automotive applications

TDK recently introduced the KCZ1210AH series of miniaturized common-mode filters for automotive applications. The series is extremely compact, measuring 1.25 (L) x 1.0 (W) x 0.5 mm (H), which contributes to a smaller footprint on substrate and provides a noise control function for different transmission signal lines for automobiles.

With an increase in advanced driver-assistance systems (ADAS), demands for automotive cameras are rapidly growing. Forward sensing cameras and cameras for around view monitors utilize common-mode filters as anti-noise products. However, as the conventional multilayer common-mode filter operates within a temperature range of -40 and +105℃, it cannot be used for ADAS cameras and was principally used in automotive accessories.

TDK’s series uses proprietary materials technology and structural design to achieve a temperature range from -55 to +125℃; it also has a rated current max of 100 and a rated voltage max of 5. By adopting a conductive resin-based electrode, it controls product cracks due to thermal shock and increases durability against mechanical stresses, such as substrate strains.

Mass-production of this series will begin in September 2021. For more information, click KCZ1210AH.
