Mechanical Characteristics
Item
Test Condition
Evaluation Standard
Solderability
Lead terminals are immersed in rosin for
5 seconds and then immersed in solder bath
of 270 ±5°C for 3 ±0.5 seconds.
The pull force should be applied to the double
lead wire:
90% min. of the stripped wires
will be wet with solder. (Except
the edge of the terminal)
Terminal Mechanical Strength
Vibration
No damage or cutting off.
Horizontal 3.0N (0.306kg) for 30 seconds
Vertical 2.0N (0.204kg) for 30 seconds
The buzzer should be measured after applying The value of oscillation
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.
The part will 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.
frequency/current consumption
should be ±10% of the initial
measurements. The SPL should
be within ±10dB compared with
the initial measurement.
