DESCRIPTION: PIEZO AUDIO TRANSDUCER
MECHANICAL CHARACTERISTICS
item
solderability¹
soldering heat resistance
terminal pull strength
vibration test
drop test
test condition
Lead terminals are immersed in rosin for 5 seconds and then im-
mersed in a solder bath of +270 ±5°C for 3 ±1.0 second.
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.
The force of 9.8 N is applied for 10 sec. to each terminal in axial
direction.
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.
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.
Notes: 1. Not recommended for wave soldering
ENVIRONMENT TEST
evaluation standard
90% min. of the lead terminals will be
wet with solder.
(except the edge of the terminal)
No interference in operation.
No damage or cutting off.
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.

RELIABILITY TEST
item
operating (life test)
test condition
1. Continuous life test:
The part will be subjected to 48 hours of continuous operation at
90°C with rated voltage applied.
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.
evaluation standard
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.
