a) temperature: +5 ~ +35°C
a) temperature: +25 ±2°C
test condition
Stripped wires of lead wires are immersed in
rosin for 5 seconds and then immersed in a
solder bath of 270 ±5°C for 3 ±0.5 seconds.
The pull force will be applied to double lead
wire:
Horizontal 4.9N (0.5kg) for 30 seconds
The part will be measured after applying a
vibration amplitude of 1.5 mm with 10 to 55 Hz
band of vibration frequency to each of the
3 perpendicular directions for 2 hours.
The part will be dropped from a height of
1 m onto a 20 mm thick wooden board 3 times
in 3 axes (X, Y, Z) for a total of 9 drops.
test condition
After being placed in a chamber at +70°C for
72 hours.
After being placed in a chamber at -20°C for
72 hours.
After being placed in a chamber at +40°C and
90±5% relative humidity for 240 hours.
The part shall be subjected to 10 cycles. One
cycle will consist of:
phone 503.612.2300 fax 503.612.2383
DESCRIPTION: electret condenser microphone
b) humidity: 45 - 85%
b) humidity: 60 - 70%
evaluation standard
evaluation standard
90% min. stripped wires will be
wet with solder.
(except the edge of the terminal)
No damage or cutting off.
After any tests, the sensitivity
should be within ±3dB compared
to the initial measurement.
The part will be measured after
being placed at +25°C for 6
hours. After any tests, the
sensitivity should be within ±3dB
compared to the initial
measurement.
