TDK expanded its ADL3225VF series (3.2 x 2.5 x 2.3 mm; L x W x T) of wire-wound inductors for automotive power-over-coax (PoC) capable of handling up to rated current of 1600mA. This groundbreaking product is set to revolutionize the automotive industry by providing enhanced power efficiency and reliability for advanced driver-assistance systems (ADAS) and other automotive applications.
Advanced driver-assistance systems (ADAS) are designed to enhance vehicle safety by using automotive cameras and sensors that monitor the driving environment. These systems rely on multiple cameras, typically installed at the front, rear, and sides of the vehicle, to capture real-time imagery for safe and secure driving. In standard configurations, automotive cameras require two separate lines for power and signal transmission: a power line connected to the vehicle’s battery and a signal line connected to the electronic control unit (ECU). However, with PoC technology, a single coaxial cable can simultaneously carry both power and data, simplifying and reducing cabling. This can reduce the vehicle’s weight, which in turn can improve fuel efficiency and lower carbon emissions.
TDK’s new ADL3225VF series implements a rated current of 1.6 A, which is equivalent to that of the ADL4532VK series (released on February 13, 2025), while achieving a reduction in the mounting area of approximately 45%. The PoC system requires a filter incorporating multiple inductors to separate power from the data signal before processing effectively. In comparison with the conventional products, ADL3225VM-2R2M, the new ADL3225VF series increases the rated current by approximately 20% by using proprietary materials and structural design innovations. At the same time, the ADL3225VF series delivers high impedance across a wide frequency range from tens of megahertz (MHz) to hundreds of megahertz. This reduces the number of inductors used, saving space. Additionally, the inductor ensures high reliability with an upper operation temperature limit of +155 °C.
