Description
Typical line capacitance = 45 pF @ 0 V
The EMIF04-1005M8 is a 4-line highly integrated
device designed to suppress EMI/RFI noise in all
systems exposed to electromagnetic interference.
This filter includes an ESD protection circuitry,
which prevents damage to the application when
subjected to ESD surges up to 15 kV on the input
pins.
