Product Description
The CM1402 is an EMI filter array with ESD protection, which integrates three pi filters (C-R-C) and two
additional channels of ESD protection. The CM1402 has component values of 20pF-47Ω-20pF, and
20pF-100Ω-20pF. 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 ±10kV, 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 ±25kV.
The ESD diodes on pins A4 and C4 ports are designed and characterized to safely dissipate ESD strikes
of ±10kV, well beyond the maximum requirement of the IEC 61000-4-2 international standard.
This device 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
CM1402 is ideal for EMI filtering and protecting data lines from ESD for the SIM card slot in mobile
handsets.
The CM1402 incorporates OptiGuard coating which results in improved reliability at assembly.The
CM1402 is available in a space-saving, low-profile Chip Scale Package.
