Highly durable inductor for automotive A2B® application
Highly durable inductor for automotive A2B®, supporting temperatures of up to 150 °C
TDK has announced its latest inductor KLZ2012-A series (2.0 mm (L) x 1.25 mm (W) x
1.25 mm (H)). These 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 new KLZ2012-A series supports operation at up to 150 °C, which is critical for its application in hightemperature
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. 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.
Main features and benefits
