EMIF01-5250SC5
Application Specific Discretes
A.S.D.
MAIN APPLICATIONS
Where EMI filtering in ESD sensitive equipment is
required :
Mobile phone : handsets and ac ces sories
RF communications
DESCRIPTION
The EMIF01-5250SC5 is a highly integrated T-filter
designed to suppress EMI / RFI noise on I/O ports
of mobile phones or RF communication
equipment.
This filter includes ESD protection circuitry which
prevents device destruction when subjected to
ESD discharges.
The comprehensive layout of the
EMIF01-5250SC5 filter allows design flexibility on
high density boards.
