The ZCAT2132-1130-BK is a black band fixed clamp filter Ferrite Core with case. Using TDK"s unique structure where the ferrite core is mounted and integrated in a plastic case, it is possible to attach them to interface cables and power cables with one touch without having to cut the cables. It features excellent absorption of high-frequency noise using the high-frequency absorption characteristics of the ferrite core. It is effective for common mode noise, so can be implemented as a noise countermeasure without influencing signal quality. It is suitable for word processors, monitors, HDDs, electronic musical instruments, video games, copiers and facsimiles.
