EMC Countermeasure Products: TDK Provides Miniaturized Common Mode Filters for Automotive High-speed Differential Transmission

      TDK Corporation has developed the KCZ1210DH series of common mode filters suitable for automotive applications. This series provides noise control for automotive high-speed differential transmission signal lines in a 1210 case size (1.25 x 1.0 x 0.5 mm)

      With the increase of advanced driver assistance systems, the demand for forward-sensing cameras and panoramic surveillance imaging systems has grown rapidly. Common mode filters are used as noise suppression products in the signal lines of cameras in autonomous vehicles. In order to process large-capacity video signals, the signal transmission rate will continue to increase to build a safe and reliable autonomous driving system.

      This product supports high-speed signals with a transmission rate of more than 10Gbps. In addition, due to the increased speed, this product also helps to control noise in the GHz band. By supporting an operating temperature range of -55 ºC to +125 ºC and using conductive resin-based electrodes, this product can control product gaps due to thermal shock while increasing durability against mechanical stress such as substrate strain. The overall dimensions are 1.25 (length) × 1.0 (width) × 0.5 mm (height), which can save board installation space.

      TDK is working to enhance the product's sensing devices for advanced driver assistance systems, and will expand its line of miniaturized common-mode filters to further support the market's need for high-speed differential signaling.
