5.7 EMC and ESD Features

EMC tests have to be performed on the application as soon as possible to detect any
potential problems.MC509 module meet the requirements of IEC61000-4-2 protocols,
contact discharge 4 kV, air discharge 8 kV.
When designing, special attention should be paid to the following:

Issue 02 (2013-05-06)
Test Condition
Frequency range: 5 Hz to 200 Hz
Acceleration: 10 m/s
Frequency scan rate: 1oct/min
Test period: 3 axial directions. Five
circles for each axial direction.
Half-sine wave shock
Peak acceleration: 300 m/s
Shock duration: 11 ms
Test period: 6 axial directions. One
shock for each axial direction.
Half-sine wave
Peak acceleration: 180 m/s

Repetition time: 6 directions. 1000
times for each direction.
First case: 0.3 m in height. Drop the
MC509 module on the marble
terrace with one surface facing
downwards twice. Six surfaces
should be tested.
Second case: 0.8 m in height. Drop
the MC509 module on the marble
terrace with one surface facing
downwards twice. Six surfaces
should be tested.
Possible harmful emissions radiated by the application to the RF receiver in the
receiver band.
ESD protection is mandatory on all signals which are externally accessible
Typically, ESD protection is mandatory for the following:
