Innovative design minimises the risk of false trips due to high inrush currents and line transients.
The TDK ACM2012 ferrite chip common-mode filter series from Abacus Polar is aimed at audio, video and other high-speed differential mode transmission, and causes almost no distortion to high-speed signals.
It is available in four specifications, including versions optimised for USB2.0 (480Mbit/s) and IEEE1394 (400 and 100Mbit/s).
The ACM2012 series is targeted at audio-video equipment that uses HDMI.
The high precision formation technology and the automatic coiling and terminal connection technologies of TDK micro core units, achieve a coupling coefficient between coils of more than 0.99.
While improving the removal of common-mode elements accumulated on signal lines, the deterioration of signal waves by differential mode impedance has been reduced to one of the lowest levels in the industry.
The products satisfy the strict HDMI TDR standard.
The outstanding performance of the ACM2012 is achieved within a form factor believed to be smaller than any comparable common-mode filter, with a footprint of just 1.3 x 2.0mm.
The device is fully RoHS compliant.
The GLF Series of chip inductors is magnetically shielded and available in the case sizes GLF1608 (0603), GLF2012 (0805) and GLF2518 (1008) as well as the low-profile versions GLF201208 and GLF251812.
The GLC2518 (1008) Series is a power inductor with a very small case size for applications which need a high current - like AC/DC inverters or small DC/DC convertors.
