The TDK ACM2012E-670-2P-T00 is a 2-line common-mode filter from the ACM-E series, designed to suppress conducted EMI on signal lines. Its 67 Ω impedance at 100 MHz targets the switching noise band common in DC-DC converters and digital interfaces.
TDK has marked the ACM2012E-670-2P-T00 as obsolete. For existing BOM lines, this part is available through independent surplus and broker channels.
The filter provides 67 Ω of common-mode impedance at 100 MHz, which is the typical suppression target for conducted EMI from switching regulators and digital clocks.
Rated for 500 mA continuous current with a maximum DC resistance of 350 mΩ. At full rated current, the DC voltage drop is under 175 mV.
