DESCRIPTION: PIEZO AUDIO TRANSDUCER
MECHANICAL CHARACTERISTICS
item
solderability¹
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 seconds.
soldering heat resistance
terminal mechanical strength
vibration test
drop test
Lead terminals are immersed up to 1.5 mm from the buzzer’s
body in a solder bath of 300 ±5°C for 3 ±0.5 seconds or 260 ±5°C
for 10 ±1 second.
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
0.75 mm with 10 ~ 55 Hz band of vibration frequency to each of
the 3 perpendicular directions for 0.5 hours.
The buzzer without packaging is subjected to 3 drops on each
axis from the height of 70 cm onto a 10 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 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
55°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 the oscillation frequency
/ current consumption should be
±10% compared to the initial
measurements. The SPL should
be within ±10dB compared to the
initial measurements.
