CM1402 SIM Card EMI Filter Array with ESD Protection 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 20 pF − 47 − 20 pF, and 20 pF − 100 − 20 pF. 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 ±10 kV, 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 ±25 kV. The ESD diodes on pins A4 and C4 ports are designed and characterized to safely dissipate ESD strikes of ±10 kV, 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 OptiGuardt coating which results in improved reliability at assembly. The CM1402 is available in a space−saving, low−profile Chip Scale Package.

SIM cards are found in all GSM cellular phones and in some other handheld devices or card readers. The ESD diodes protect the controller against possible ESD strikes that may occur when the connector pins are exposed during direct contact, or during insertion of the SIM card into the card slot. The EMI filter suppresses all high−frequency noise, preventing the unwanted EMI signals from both entering and exiting the main board. The signals that interface with the SIM card are the Reset, the Clock and the bidirectional data I/O, as shown in Typical Application Diagram for the SIM Card Interface. Note: One channel of the CM1402 with a zener diode is not shown on the diagram. Figure 5. Typical Application Diagram for the SIM Card Interface For best filter and ESD performance, both GND bumps (B1, B2) of the CM1402 should be directly connected to the Ground plane. A small capacitor of about 1 F is required next to the VCC pin of the SIM connector in order to improve stability of the SIM card supply rail.
