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.

MECHANICAL CHARACTERISTICS

item

test condition

solderability

Stripped wires are immersed in rosin for

5 seconds and then immersed in solder bath

of 230 ±5°C for 3 ±1 seconds.

soldering heat resistance

Stripped wires 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.

lead wire pull strength

The pull force shall be applied to lead wire:

Horizontal

3.0N for 30 seconds

Vertical

2.0N for 30 seconds

vibration

The buzzer shall 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 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.

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.
