3-terminal Filters(SMD)
For Wide-band
MEM Series MEM2012P Type
FEATURES
• Multilayer chip EMC filter that is small and low-profile due to the
use of a
π-type
circuit.
• Entirely monolithic structure results in high reliability.
• Due to closed magnetic circuit architecture, high-density
installation becomes possible, and crosstalk generation is
prevented.
• Steep attenuation characteristic plot. Highly effective noise
suppression.
• Covers a wide range of frequencies.
•
π-type
circuit with 1 coil /2 capacitors construction.
APPLICATIONS
Computers, computer peripherals, VCRs, TVs, car audio equip-
ment, printers, game machines, etc.
