KCZ-AH Soft-Termination Common-Mode Filter

TDK's KCZ-AH series of miniaturized common-mode filters was designed for use in automotive applications. The series is extremely compact, measuring 1.25 mm (L) x 1.0 mm (W) x 0.5 mm (H), which contributes to a smaller footprint on the 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. Conventional multilayer common-mode filters operate within a temperature range of -40°C to +105°C and cannot be used for ADAS cameras. TDK's series uses proprietary materials technology and structural design to achieve a temperature range from -55°C to +125°C. The KCZ-AH series also has a rated current max of 100 V and a rated voltage max of 5 V, and 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.
