Application Smart electronic devices, medical electronic devices and more Description of SMD piezo buzzer: 1 - LCP is applied as housing material with properties including heat resistance and acid-alkali resistance 2 - Well-chosen yellow grass is applied as lead pin material in order to provide best welding property to the product.
3 - Piezoelectric interaction operation mode can save considerable power than magnetic buzzer 4 - Tiny size of the product adapts to more multiple PCB space design.
It meets the trend of making electronic products ultimately small and thin.
5 - Mature SMD design perfectly meets the SMT requirements which greatly improved welding efficiency.
6 - Steadily effective distance of sound output is very suitable for a wide range of portable electronic devices 7 - Flexible voltage application is allowable for this product 8 - ROHS Directive-compliant
