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.

Reliability Test

Item Test Condition

Operating (Life Test) 1. Continuous life test:

The part will be subjected to 48 hours of

continuous operation at +70°C with rated

voltage applied.

2. Intermittent life test:

A duty cycle of 1 minute on, 1 minute off, a

minimum of 5,000 times at room temp

(+25±2°C) with rated voltage applied.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 ±10dB compared to the initial measurements.
