ENVIRONMENT TEST

item

test condition

high temp. test

After being placed in a chamber at +70°C for

72 hours.

low temp. 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% relative humidity for 240 hours.

temp. cycle test

The part shall be subjected to 10 cycles. One

cycle will consist of:

evaluation standard

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.

MECHANICAL CHARACTERISTICS

item

test condition

soldering heat resistance

Soldering iron of 270 ±5°C should be placed on

the terminal for 2 ±0.5 seconds.

PCB wire pull strength

The pull force will be applied to double lead

wire:

Horizontal 4.9N (0.5kg) for 30 seconds

vibration

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.

drop test

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.

evaluation standard

No interference in operation.

No damage or cutting off.

After any tests, the sensitivity

should be within ±3dB compared

to the initial measurement.
