The CM1402 has component values of 20pF-47 Ω-20pF, and 20pF-100 Ω-20pF. The parts include avalanche- type ESD diodes on every pin, which provide a very high level of protection for sensitive electronic compo- nents 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 require- ment 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 pro- tected 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 elec- tronics (e.g. mobile handsets, PDAs, notebook com- puters) 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 with optional lead-free finishing.
