Description of SMD magnetic buzzer:
-
LCP is applied as housing material with properties including heat resistance and acid-alkali resistance
-
Well-chosen yellow grass is applied as lead pin material in order to provide best welding property to the product.
-
Tiny size of the product adapts to more multiple PCB space design.It meets the trend of making electronic products ultimately small and thin.
-
Mature SMD design perfectly meets the SMT requirements which greatly improved welding efficiency.
-
Steadily effective distance of sound output is very suitable for a wide range of portable electronic devices
-
Rated square wave output and rated voltage are needed
-
ROHS Directive-compliant
