A high impedance laminated common-mode filter for alleviating the noise of ultra-high speed vehicle interfaces

     TDK Corporation has announced the launch of the new KCZ1210DH800HRTD25 common mode filter (1.25 x 1.0 x 0.5 ㎜ -- length x width x height) for ultra-high speed automotive interface. The KCZ1210DH800HRTD25 common mode filter design for automotive is compact, Size is only 1.25 ㎜ x 1.0 ㎜ x 0.5 ㎜. The operating temperature ranges from -55 ° C to +125 ° C.

     This product is the latest addition to the KCZ1210DH line, which was launched in February 2022. Compared with the traditional filter, noise control function of the product, received a significant boost in 1 ㎓ impedance is 1000 Ω, insertion loss more than 25 dB. With the increasing use of advanced Driver assistance systems (ADAS), signal processing speeds have increased significantly. Through this, safer and more reliable autonomous driving will be achieved. TDK's new filter helps prevent errors associated with forward-sensing cameras, ㎜Wave radar, LiDAR (Laser radar), etc., during high-speed signal processing.

     TDK's proprietary internal electrode pattern arrangement and integrated sintered configuration of the best low-dielectric materials achieve excellent performance and long-term stability. This product reduces the risk of cracking by adding a conductive resin base to the end electrode. Not only that, the product also enhances durability against mechanical stresses such as substrate strain.

     TDK offers a diverse portfolio of laminated automotive products, including SMT magnetic beads for use at temperatures up to 150 ° C and common-mode filters for reducing radiated noise during high-speed differential transmission. In the future, we will continue to work on noise control products and services to help improve communication quality in increasingly fast autonomous driving systems.
