SPECIFICATION OF WCM SERIES
FEATURES
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.
