8.4 ESD Characteristics

NL668-LA series module design has considered ESD issue and provided ESD protect measurements, but
take ESD issue taken by module carrier and secondary development into consideration, developers
should care ESD protection of module application terminal. In addition to considering anti-static treatment
of packaging, please refer to recommended circuit of interface design in the document.

Test Condition
Temperature -40℃± 3℃, 24 hours in shutdown state
Temperature +85℃± 3℃, 24 hours in shutdown state
In shutdown state, 0.5 hour at -40℃ and +85℃ environment
respectively, the temperature conversion time < 3min, for 24 cycles
Temperature +85℃± 3℃, humidity 90–95% RH, 24 hours in shutdown
state
Temperature +75℃± 3℃, 24 hours in operating state
When the frequency is 5Hz to 20Hz, the random vibration ASD
(Acceleration Spectral Density) is 0.96m2/s3. When the frequency is
20Hz to 500Hz, the random vibration ASD is 0.96 m2/S3 (20Hz). For
other frequencies, the random vibration ASD is -3dB/octave.
