1. We use the “Pascal (Pa)” indication of sensitivity as per the recomendation of I.E.C. (International Electrotechnical Commission). The sensitivity of “Pa” will increase
20dB compared to the “ubar” indication. Example: -60dB (0dB = 1V/ubar) = -40dB (1V/Pa)
2. All specifications measured at 5~35°C, humidity at 45~85%, under 86~106kPa pressure, unless otherwise noted.

MECHANICAL CHARACTERISTICS
item
test condition
evaluation standard
soldering heat resistance
Stripped wires are immersed in rosin for 5 seconds and then immersed in solder bath of 270 ±5°C for 3 ±0.5 seconds.
90% min. stripped wires should be wet
with solder (except edge of terminal).
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 100 cm onto a 20 mm thick wooden
board.
The sensitivity should be within
±3dB compared with the initial
measurement.
ENVIRONMENT TEST
item
test condition
evaluation standard
high temperature test
After being placed in a chamber at +80°C for 1 hour.
low temperature test
After being placed in a chamber at -30°C for 1 hour.
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:
+80к
+25к
+25к
-30к

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.
