(Except 5 seconds and then immersed in solder bath the edge of the terminal) of +270 ±5°C for 3 ±1 seconds. Lead terminals are immersed up to 1.5mm from No interference in operation. buzzer’s body in solder bath of +300±5°C for 3±0.5 seconds or 260±5°C for 10±1 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.
