EMIF01-5250SC5

EMI FILTER

WITH ESD PROTECTION

MAIN APPLICATIONS

Where EMI filtering in ESD sensitive equipment is

required :

Mobile phone : handsets and accessories

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.

SOT23-5L (SC-59A)
