California Micro Devices&prime CM1437 is an EMI filter array with ESD protection, which integrates either four or eight pi filters (C-R-C). The CM1437 has component values of 7.5pF-200-7.5pF (fC = 210MHz). The parts include ESD protection diodes on every pin, providing 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 safely dissipate ESD strikes of ±15kV contact discharge, twice the specification requirement of the IEC 61000-4-2, Level 4 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.

CM1437 is particularly well-suited for portable electronics (e.g. mobile handsets, PDAs, notebook computers) because of its small package and easy-to-use pin assignments. In particular, the CM1437 is ideal for EMI filtering and protecting data lines from ESD in wireless handsets.

The CM1437 is available in space-saving, low-profile, 0.4mm pitch, 8- and 16-lead TDFN packages. It is fabricated with California Micro Devices&prime Centurion™ process and available with optional lead-free finishing.
