ALC2012 & ALC2012H Common Mode Filters

TDK ALC2012 and ALC2012H Common Mode Filters are downsized wound-type chip common mode filters for Ethernet applications. The filters feature a suppressed differential mode impedance range, which means there is virtually no effect on high-speed signals. The ALC2012 series is ideal for high-speed and general differential signal lines. The ALC2012H series is for ultra-high-speed differential signal lines. TDK ALC2012 and ALC2012H Common Mode Filters are RoHS compliant and operate within a -40°C to +85°C temperature range.
