MECHANICAL CHARACTERISTICS
item
test condition
evaluation standard
soldering heat resistance
Soldering iron with 270 ±5°C should be applied on the terminal for
2 ±0.5 seconds.
No interference in operation.
PCB wire pull strength
The force of 4.9 N is applied for 30 sec. to double lead wire.
No damage or cutting off.
vibration test
The microphone should be measured after a vibration amplitude
of 1.5 mm with 10 ~ 55 Hz band of vibration frequency to each of
the 3 perpendicular directions for 2 hours.
drop test
The microphone without packaging is subjected to 3 drops on
each axis from the height of 1 m onto a 10 mm thick wooden
board.
The sensitivity should be within
±3dB compared with the initial
measurement.
ENVIRONMENT TEST
item
test condition
high temperature test
After being placed in a chamber at +70°C for 72 hours.
evaluation standard
low temperature test
After being placed in a chamber at -20°C for 72 hours.
humidity test
After being placed in a chamber at +40°C and 90 ±5% RH for
240 hours.
temperature cycle test
The part will be subjected to 10 cycles. One cycle will consist of:
+70к
+25к

The microphone will be measured
after being placed at +25°C for 6
hours. The value of the oscillation
frequency should be ±10% compared
to the initial measurements. The SPL
should be within ±3dB compared to
the initial measurements.
