Seiwa E04SRM472715 SR, SRM and SRS Types Split Cores

Made in Japan
Manufacturer: SEIWA ELECTRIC MFG.CO.,LTD
Model: E04SRM472715

Features

The ferrite’s high frequency wave absorption characteristic is effectively used to absorb high frequency noise.
Since the ferrite core is integral with its plastic resin case, it can be fitted to an interface or power cable very easily.
The ferrite core effectively suppresses common mode noise without any unfavorable influence on the quality of signals.
The ferrite core is available in a variety of sizes to suit different cable diameters.
Case material: Nylon 66 (UL94 V-0)
We also supply a range of models which match a cable diameter of 19mm.
