TDK's Clamp Filters ZCAT series uses a unique structure where the ferrite core is mounted and integrated in a plastic case so that it can be snapped on without disconnecting any interface cable or power cable. Using the high-frequency absorption characteristics of the ferrite core, it provides excellent absorption of high frequency noise and is highly effective as countermeasure against common mode noise without adverse effect on signal quality. It is compatible with various cable sizes. There are also products for automotive use.
