NOTES1. The value of C501/C502 should be less than 1uF.

2. U501/U502 is used for protecting SIM card against ESD, and the junction capacitance should be less than 50pF.

3. For MC60 module, ground of SIM card is recommended to be routed to the Pin 16 ("SIM_GND") of the module separately.

It should be placed nearby SIM card holder.
