EMC Components: TDK announces new miniaturized, common-mode filters for high-temperature automotive applications

• Maximum operating temperature: 125°C
• The conductive resin-based electrode is highly durable

TDK Corporation (TSE:6762) today announced the development of its 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.

TDK is working to enhance its inductive devices for ADAS and will expand its line of miniaturized common-mode filters supporting higher-speed differential signals. Mass-production of this series will begin in September 2021.

Main applications

• High-speed interface (USB2.0, LVDS, etc.)
• Advanced driver-assistance systems (ADAS)

Main features and benefits

• Operable at 125°C, the maximum temperature
• Adoption of a conductive resin-based electrode reduces mechanical and thermal stresses
