The CM1424 is an EMI filter array integrating 3 pi-filters (C-R-C) and 2 channels of ESD protection. The CM1424 has component values of 12pF-100-12pF. The parts include avalanche-type 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). 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 IEC61000-4-2 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.

CM1424 ESD diodes on pins A2 and C2 ports are also designed and characterized to safely dissipate ESD strikes of ±15kV, well beyond the maximum requirement of the IEC 61000-4-2 international standard.

CM1424 is particularly well suited for portable electronics (e.g. mobile handsets, PDAs, notebook computers) because of its small package format and easy-to-use pin assignments. In particular, the CM1424 is ideal for EMI filtering and protecting data lines from ESD for the MultiMedia Card (MMC) slot in mobile handsets.

The CM1424 devices are optionally available with OptiGuard™ coating which results in improved reliability. The CM1424 is available in space-saving, low-profile, chip-scale packages with optional lead-free finishing.
