CM1421 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 subjected to electrostatic discharge (ESD). The ESD diodes connected to the filter ports are designed and characterized to safely dissipate ESD strikes of ±15kV, beyond the maximum requirement of the IEC 61000-4-2 international standard. Using the MIL-STD-883 (Method 3015) specification for Human Body Model (HBM) ESD, the pins are protected for contact discharges at greater than ±30kV.



    This device is particularly well suited for portable electronics (e.g. wireless handsets, PDAs, notebook computers) because of its small package format and easy-to-use pin assignments. In particular, the CM1421 is ideal for EMI filtering and protecting data lines from ESD for the LCD display in clamshell handsets.



    The CM1421 incorporates Optiguard? coating which results in improved reliability. The CM1421 is available in space-saving, low-profile chip-scale packages with optional lead-free finishing.
