What 700 Ohms at 100 MHz means for a power rail
The ACM70V-701-2PL-TL00: The 700 Ohm impedance at 100 MHz is the common-mode attenuation peak for conducted noise in the 10-500 MHz range — typical for switching regulators, motor drives, and CAN/FlexRay transients. Rated 4 A continuous current with a maximum DC resistance of 15 mOhm, so the I²R loss at full load stays under 0.24 W — no derating needed in a 125°C under-hood ambient.
Surface-mount — the J-lead forms a low-profile solder joint on the PCB land pattern, typical for space-constrained ECU or sensor module layouts.
