Measurement Method
S.P.L. Measuring Circuit Mic: RION S.P.L. meter UC 30 or equivalent
Mechanical Characteristics
Item Solderability Evaluation Standard Test Condition 90% min. of the lead terminals Lead terminals are immersed in rosin for will be wet with solder. (Except 5 seconds and then immersed in solder bath the edge of the terminal) of +270 5C for 3 1 seconds. Lead terminals are immersed up to 1.5mm from No interference in operation. buzzer's body in solder bath of +3005C for 30.5 seconds or 2605C for 101 seconds. No damage or cutting off. For 10 seconds, the force of 9.8N (1.0kg) is applied to each terminal in axial direction. The value of oscillation The buzzer will be measured after applying frequency/current consumption a vibration amplitude of 1.5 mm with 10 to should be 10% of the initial 55 Hz band of vibration frequency to each of measurements. The SPL should the 3 perpendicular directions for 2 hours. The part will be dropped from a height of 75 cm be within 10dB compared with the initial measurement. onto a 40 mm thick wooden board 3 times in 3 axis (X, Y, Z) for a total of 9 drops.

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 within 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 +70C with rated voltage applied. 2. Intermittent life test: A duty cycle of 1 minute on, 1 minutes off, a minimum of 5,000 times at room temp (+252C) 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 10dB compared to the initial measurements.
