Specifications and operating details
The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.
- vibration test The microphone 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 sensitivity should be within ±3dB compared with the initial measurement.drop test The microphone without packaging is subjected to 3 drops on each axis from the height of 100 cm onto a 20 mm thick wooden board.
- ENVIRONMENT TEST item test condition evaluation standard high temperature test After being placed in a chamber at +80°C for 1 hour.
- The microphone will be measured after being placed at +25°C for 6 hours.
- The value of the oscillation frequency should be ±10% compared to the initial measurements.
- low temperature test After being placed in a chamber at -30°C for 1 hour.
- humidity test After being placed in a chamber at +40°C and 90 ±5% RH for 240 hours.

Engineering review checklist
- Check resistance value, tolerance, temperature coefficient and long-term stability over the operating range.
- Derate continuous power for ambient temperature and verify pulse or surge capability separately.
- Match the land pattern, termination finish and current-sense routing to the exact package option.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
