test condition
Lead terminals are immersed in a solder bath of +350 ±5°C for 3
±1 seconds.
Refer to the Recommended Temperature Profile for Reflow Oven.
For 10 seconds, the force of 9.8 N (1.0 kg) is applied from behind
the part which is soldered onto the PC Board.
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.
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.
test condition
After being placed in a chamber at +120°C for 240 hours.
After being placed in a chamber at -40°C for 240 hours.
After being placed in a chamber at +40°C and 90 ±5% RH for
240 hours.
The part will be subjected to 5 cycles. One cycle will consist of:
test condition
1. Continuous life test:
The part will be subjected to 48 hours of continuous operation at
55°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.
