MCU Boards
DESCRIPTION
The EMIF02-600FU7 isa highlyintegrated array designed
to suppress EMI / RFI noise in all systems subjected to
electromagnetic interferences.
Additionally, this filter includes an ESD protectioncircuitry
whichprevents theprotected devicefrom destructionwhen
subjected to ESD surges up to 15 kV. The
EMIF02-600FU7 provides best efficiency when using
separated inputs and outputs, in the so-called 4-points
structure.

TECHNICAL INFORMATION
FREQUENCY BEHAVIOR
The EMIF02-600FU7 is firstly designed as an EMI/RFI filter. This low-pass filter is characterized by the following
parameters:
- Cut-off frequency
- Insertionloss
- High frequency rejection
FigA1: EMIF02- 600F U 7frequencyresponsecurve.
Figure A1gives these parameters, in particularthe signal rejection at theGSM frequency is about -20dBm at 900MHz,
while theattenuation for FM broadcast range(around 100MHz) is better than -32dBm
