hours. The SPL should be within
±10 dBA when compared with the
initial measurement.
Mechanical Characteristics
Item
Test Condition
Solderability
Lead terminals are immersed in rosin for
5 seconds and then immersed in solder bath
of 270 ±5°C for 3 ±1 seconds.
Soldering Heat Resistance
Lead terminals are immersed up to 1.5mm from
buzzers body in solder bath of 260 ±5°C for
3 ±1 seconds.
Terminal Mechanical Strength
For 10 seconds, the force of 9.8N (1.0kg) is
applied to each terminal in axial direction.
Vibration
The buzzer should 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 should be dropped from a height of
75 cm onto a 40 mm thick wooden board 3
times in 3 axes (X, Y, Z) for a total of 9 drops.
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.
After the test, the part should
meet specification without any
damage in appearance. The SPL
should be within ±10 dBA
compared with the initial
measurement. Part No: CEM-1205C
