5 IoT and smart home devices: Utilized in smart locks, smoke detectors, or security cameras for alarm notifications

6 Toys and gaming devices: Incorporated into electronic toys or handheld games for interactive sound feedback

7 Communication devices: Used in walkie-talkies or intercom systems for call alerts or connection status indicators

注意事项 PRECAUTIONS

1 Soldering: Follow the recommended reflow soldering profile (peak temp ≤260°C); if stored for over 48 hours at humidity >60%, dry at 120°C for 24h before soldering

2 Voltage: Do not exceed maximum operating voltage of 25Vp-p to avoid component damage

3 Temperature: Avoid exposure to temperatures outside -40°C to85°C (operating) or -40°C to85°C (storage)

4 Handling: Prevent mechanical impact/pressure on the buzzer surface to protect internal piezo elements

5 Application: Not recommended for life-support or safety-critical systems (per manufacturer disclaimer)

6 PCB Layout: Adhere to the provided mechanical drawing dimensions for optimal performance

7 RoHS Compliance: Ensure compatibility with RoHS requirements in your application
