Power-line common-mode choke, 8 A continuous
The TDK ACM1211-701-2PL-TL01 is a two-line common-mode filter from the ACM series, built for power-line EMI suppression. It carries 8 A continuous with a DCR of 6 mOhm max — the low resistance means minimal heat in the power path, so it fits on a supply rail without derating for self-heating. Impedance hits 700 Ohms at 100 MHz, which knocks down conducted common-mode noise in the 30-300 MHz range — the band where most switching-regulator harmonics live. The 80 V DC rating covers 48 V telecom rails and 60 V industrial buses with margin.
Board-fit and temperature range
Surface-mount in a horizontal 4-pad package, 12.0 x 11.0 mm footprint, 6.0 mm seated height. The low profile suits tight enclosures where a vertical can would hit the lid. Operating from -40 to 85 °C, it handles outdoor cabinet duty and unheated factory floors.
