Product Description

The CM1421 is a multichannel array consisting of four low-pass filters with integrated ESD protection and four ESD-only protection channels designed to reduce EMI/RFI emissions on LCD data lines in mobile handsets. The CM1421 has component values of 15pF-100?-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 sub jected to electrostatic discharge (ESD).
