Murata is continuing to support ongoing engineering progression within the automotive sector with the launch of the LQW21FT_0H series. These are claimed to be the world’s smallest inductors with broadband impedance for in-vehicle PoC circuit of SerDes-based interfacing. The series is compliant with AEC-Q200 and offers a combination of both broadband impedance and high-current performance. With its state-of-the-art technologies for both ceramic material and coil structure, the company can supply these components in a space-saving size format that other manufacturers cannot match. They are contained in a compact 0805-inch case size, with 2mm x 1.2mm x 1.6mm dimensions.
This series of inductors are remarkably well suited to PoC use cases. As well as their raised broadband impedance levels, they display superior saturation properties. Inductance values from 0.47µH to 2µH can be specified, with respective current ratings of 1A and 0.45A. The heightened operating temperatures that these inductors can support make them ideal for automotive implementation (reaching up to 125C).
“To accelerate the transition towards safe, autonomous driving, the number of built-in cameras featured in vehicle models continues to increase,” said Uwe Mirschberger, product manager EMI – Filters, Inductors, at Murata Europe. “The popularity of PoC for in-vehicle applications is, as a result, steadily rising and enables significant reductions in cabling weight by transmitting imaging data and electrical power over one coaxial cable. Keeping the power and data signals separate from one another is, of course, vital to PoC implementations, and LQW21FT_0H’s broad frequency characteristics help to reduce the number of inductors needed for this purpose. The LQW21FT_0H series has the ability to make a real difference to PoC deployments, enabling the number of inductors required to be reduced considerably. Consequently, engineers will be able to streamline their designs by saving space and reducing the total DC resistance too.”
