Mechanical Characteristics
Item Solderability (Connector excepted) Terminal Mechanical Strength Test Condition Stripped wires of lead wires are immersed in rosin for 5 seconds and then immersed in a solder bath of +270 5C for 3 0.5 seconds. The pull force should be applied to the double lead wire: Horizontal 3.0N (0.306kg) for 30 seconds Vertical 2.0N (0.204kg) for 30 seconds 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. 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 stripped wires will be wet with solder. (Except the edge of the terminal) No damage or cutting off.
Vibration
Drop Test
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.
Environment Test
Item High temp. test Low temp. test Humidity test Temp. cycle test Test Condition After being placed in a chamber at +95C for 240 hours. After being placed in a chamber at -40C for 240 hours. After being placed in a chamber at +40C and 905% relative humidity for 240 hours. The part shall be subjected to 5 cycles. One cycle will consist of: Evaluation Standard
The buzzer will be measured after being placed at +25C 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.

Reliability Test
Item Operating (Life Test) Test Condition 1. Continuous life test: The part will be subjected to 48 hours of continuous operation at +65C 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 2C) with rated voltage applied. Evaluation Standard The buzzer will be measured after being placed at +25C 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.
Test Conditions
Standard Test Condition Judgement Test Condition a) Tempurature: +5 ~ +35C a) Tempurature: +25 2C b) Humidity: 45 - 85% b) Humidity: 60 - 70% c) Pressure: 860-1060 mbar c) Pressure: 860-1060 mbar
