3-terminal Filters(SMD)
For Signal Line
MEM Series MEM2012D Type
This chip type EMC filter eliminates the noise component from a
communication line. This noise component can be eliminated by
inserting this products in series with the communication line.
In comparison to earlier multilayer chip EMC filters, signal wave-
form distortion is low after the signal has passed through the filter.
Therefore this filter can be used for high speed pulse signal circuits
and wide band analog RGB circuits.
FEATURES
•Small size (L2× W1.25× T0.85mm).
• Steep attenuation characteristic.
• Low distortion of signal after passing through filter.
• SMD product that can use taped packaging for automatic
mounting.
• Capable of reflow soldering.
TEMPERATURE RANGES
APPLICATIONS
Single line noise elimination for PCs, CRTs, LC display panels,
printers, game machines, DVD equipment, etc.
