MECHANICAL CHARACTERISTICS
item
test condition
evaluation standard
solderability1
Lead terminals are immersed in rosin for 5 seconds and then immersed in a solder bath of +270 ±5°C for 3 ±1.0 second.
90% min. of the lead terminals will be
wet with solder.
(except the edge of the terminal)
soldering heat resistance
Lead terminals are immersed up to 1.5 mm from the buzzer’s
body in a solder bath of 260 ±5°C for 3 ±1 seconds.
No interference in operation.
terminal pull strength
The force of 9.8 N is applied for 10 sec. to each terminal in axial
direction.
No damage or cutting off.
vibration test
The buzzer 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 buzzer without packaging is subjected to 3 drops on each
axis from the height of 75 cm onto a 40 mm thick wooden board.
The buzzer will be measured after
being placed at +25°C for 4 hours.
The value of oscillation frequency /
current consumption should be ±10%
of the initial measurements. The SPL
should be within ±10dB compared
with the initial measurement.
Notes:
1. Not recommended for wave soldering
ENVIRONMENT TEST
item
test condition
evaluation standard
high temperature test
After being placed in a chamber at +105°C for 240 hours.
low temperature test
After being placed in a chamber at -40°C for 240 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 5 cycles. One cycle will consist of:
The buzzer will be measured after
being placed at +25°C for 4 hours.
The value of the oscillation frequency
/ current consumption should be
±10% compared to the initial
measurements. The SPL should
be within ±10dB compared to the
initial measurements.
RELIABILITY TEST

operating (life test)
1. Continuous life test:
The part will be subjected to 48 hours of continuous operation at
90°C with rated voltage applied.
The buzzer will be measured after
being placed at +25°C for 4 hours.
The value of oscillation frequency /
current consumption should be ±10%
of the initial measurements. The SPL
should be within ±10dB compared
with the initial measurement.
2. Intermittent life test:
A duty cycle of 1 minute on, 1 minute off, a minimum of 5,000
times at room temp (+25 ±2°C) with rated voltage applied.
TEST CONDITIONS
standard test conditions
a) Temperature: +5 ~ +35°C
b) Humidity: 45 ~ 85%
c) Pressure: 860 ~ 1060 mbar
judgement test conditions
a) Temperature: +25 ±2°C
b) Humidity: 60 ~ 70%
c) Pressure: 860 ~ 1060 mbar
