3-terminal Filters(SMD)
For Signal Line
MEM Series MEM2012T Type
FEATURES
• Multilayer chip EMC filter utilizing a T-type circuit.
• Entirely monolithic structure results in high reliability.
• Due to closed magnetic circuit architecture, high-density installa-
tion becomes possible, and crosstalk generation is prevented.
• Steep attenuation characteristic plot. Highly effective noise sup-
pression.
• Covers a wide range of frequencies.
• MEM2012T is a coil type EMC filter.
APPLICATIONS
Computer and computer peripherals, VCRs, TVs, car audio equip-
ment, printers, game machines, etc.
