TDK Corp. has launched its ADL3225VM high-current inductors in a 3225 (3.2 × 2.5 × 2.5 mm) package size for automotive power over coax (PoC) systems. The inductors reportedly achieve the highest rated current in the 3225 package size. In addition, the proprietary structural design and wire winding manufacturing process delivers high impedance over a broad bandpass frequency of 1 MHz up to 1 GHz, said the company.

The AEC-Q200 inductors target PoC in advanced driver-assistance systems (ADAS) camera system circuits. “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,” said TDK. “Low-voltage differential signaling (LVDS) with transmission rates of up to 1.5 Gbits/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.”
The ADL3225VM-2R2M-TL000 and ADL3225VM-150M-TL000 inductors provide an inductance of 2.2 μH and 15 μH, respectively, both with a +/-20% tolerance. The DC resistance (max) ratings for the ADL3225VM-2R2M-TL000 and ADL3225VM-150M-TL000 are 0.18 Ω (180 mΩ) and 0.40 Ω (400 mΩ), respectively. The devices operate over a temperature range of -55°C and 155°C.
Rated current for the ADL3225VM-2R2M-TL000 and ADL3225VM-150M-TL000 are 1.22 A (40°C rise) and 725 mA (40°C rise), respectively. Rated current is shown below in the table.
