Measurement Method

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

buzzer’s body in solder bath of +300±5°C for

3±0.5 seconds or 260±5°C for 10±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 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 will 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

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.
