DESCRIPTION
The EMIF04-1502QCF is a 4 line highly integrated
device designed to suppress EMI/RFI noise in all
systems subjected to electromagnetic interferences.
This filter includes an ESD protection circuitry,
which prevents the device from destruction when
subjected to ESD surges up 15kV on the input
pins.
QFN 2x2mm 8 pins
(Dot on package indicates pin 1)
