4-Channel EMI Filter Array with ESD Protection for SIM Card Applications

CM1423 is an EMI filter array with ESD protection, which integrates three pi filters (C-R-C) and two additional channels of ESD protection. The CM1423 has component values of 20pF-47 Ohm-20pF,and 20pF-100 Ohm-20pF. The parts include avalanchetype ESD diodes on every pin, which provide a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD).
