Mechanical Characteristics
Item Test Condition
Solderability Lead terminals are immersed in rosin for
5 seconds and then in a solder bath of
+270 ±5°C for 3 ±1 seconds.
Soldering Heat Resistance Lead terminals are immersed up to 1.5mm from
the buzzer’s body in a solder bath of
+260 ±5°C for 3 ±1 seconds.
Terminal Mechanical Strength The force of 9.8 N (1.0 kg) will be applied
to each terminal in each axial direction for
10 seconds.
Vibration The buzzer 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 is to be dropped from a height of
75 cm onto a 40 mm thick wooden board 3
times in 3 axis (X, Y, Z) for a total of 9 drops.
Evaluation Standard
90% min. of the lead terminals
must be wet with fresh solder.
