(except the edge of the terminal) soldering heat resistance Lead terminals are immersed up to 1.5 mm from the buzzer’s body in a solder bath of 260 ±5°C for 3 ±1 seconds. No interference in operation. terminal pull strength The force of 9.8 N is applied for 10 sec. to each terminal in axial direction. No damage or cutting off. vibration test The buzzer should be measured after a vibration amplitude of 1.5 mm with 10 ~ 55 Hz band of vibration frequency to each of the 3 perpendicular directions for 2 hours. drop test The buzzer without packaging is subjected to 3 drops on each axis from the height of 75 cm onto a 40 mm thick wooden board. The buzzer will be measured after being placed at +25°C for 4 hours. 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. Notes: 1. Not recommended for wave soldering ENVIRONMENT TEST item test condition evaluation standard high temperature test After being placed in a chamber at +105°C for 240 hours. low temperature test After being placed in a chamber at -40°C for 240 hours. humidity test After being placed in a chamber at +40°C and 90 ±5% RH for 240 hours. temperature cycle test The part will be subjected to 5 cycles. One cycle will consist of: 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. RELIABILITY TEST item test condition evaluation standard operating (life test) 1. Continuous life test: The part will be subjected to 48 hours of continuous operation at 90°C with rated voltage applied. The buzzer will be measured after being placed at +25°C for 4 hours. 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. 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.
