The CM1420 and CM1422 is an EMI filter arrays with ESD protection, which integrate six or eight Pi filters C-R-C). The CM1420 has component values of 15pF-100Ω-15pF. These devices include ESD protection diodes on every pin, which provide a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD).
