Product Description
The CM1423 is an EMI filter array with ESD protection, which integrates six Pi- filters (C-R-C) and four channels of ESD protection. The CM1423’s filters have component values of 12pF-100Ω-12pF. The part includes 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).
