Product Name : WCM
For USB2.0 IEEE1394 Lan Interface

Model : WCM


<
SMD COMMON MODE CHOKE --> WCM TYPE
 

FEATURE
Lowprofile and very small size SMD Design;
Wound Chip constructure with standard 0805
and 1206 size; with best EMI suppression effect
but least impact to data signal wave form.

APPLICATIONS
Preventive measure against high speed signal
radiation emissions such as USB 2.0;
IEEE1394 or LAN interface.
Best for NB; DSC; mobile device design.
