KLZ2012MHR3R3ATD69 Inductor

TDK Corporation's KLZ2012-A series multilayer inductors are designed for automotive audio bus (A²B) applications with a wide operation range, high durability, and superior inductance tolerance.

With the recent rapid evolution of advanced driver-assistance systems (ADAS) and autonomous driving technologies, automobiles are equipped with a variety of sensors such as cameras, radars, and LiDAR, leading to a dramatic increase in electronic equipment. Moreover, automotive infotainment systems not only provide streaming services of music, videos and other multimedia content, navigation, and internet connectivity inside vehicles, but they also communicate with outside systems. A²B is a technology designed to reduce the weight of cable harnesses consisting of a wide variety of these telecommunication buses, aiming at its final goal of increased fuel efficiency of automobiles.

The KLZ2012-A series is suitable for high-temperature environments and supports operation at up to +150°C, which is critical for its application in high-temperature automotive environments. Additionally, thanks to the conductive resin of the external electrode, it is durable against mechanical stresses and thermal shocks. As A²B is a differential signal interface, it needs to reduce variability in nodes. The KLZ2012-A series achieves inductance tolerance of ±8% or less within the same lot, contributing to the reduction of spurious harmonics generated by variability in inductance.
