TDK releases industry’s highest rated current inductors for automotive Power over Coax systems

TDK recently launched its newly developed ADL3225VM inductors for use in automotive Power over Coax (PoC) systems. Measuring at 3.2 x 2.5 x 2.5mm (L x W x H), these inductors provide a compact solution for designers looking to reduce vehicle weight as manufacturers add more sensors and cameras to accommodate expanding automotive and advanced driver-assistance systems (ADAS) applications. The proprietary structural design and wire winding manufacturing process ensure high impedance over a broad bandpass of 1MHz up to 1GHz. The inductors are compliant with AEC-Q200 and achieve the highest-rated current in the industry for the 3225 size*. Volume production began in October 2021.

Performance advancements of ADAS applications have resulted in the increased production of electric control units (ECUs), particularly around view cameras and front sensing cameras, escalating the need for high-speed interfaces. Low-voltage differential signaling (LVDS) with transmission rates of up to 1.5 Gbit/s transfer image signals from automotive cameras to the control circuit board. This process involves PoC systems that Relay data and power over the same coaxial cable. TDK’s ADL3225VM inductors serve as a blocking coil that separates ringing currents from the power supply, and increases the currents supplied by PoC systems. They support operating temperatures between -55 ℃ and +155 ℃.
