D.TTING METHOD
Standard Measurement conditions
Temperature:25±2℃ Humidity:45-65%
Acoustic Characteristics:
The oscillation frequency, current consumption and sound prsure are measured by the measuring instruments shown below
In the measuring tt, buzzer is placed as follows:
E. Tical Frequency Rponse Curve
F. Recommend Driving Circuit 
The base current Ib should high eugh so that it saturat the collector current of the transistor with the CB load.
G. Soldering Condition
(1)Recommendable reflow soldering condition is as follows
(Reflow soldering is twice)
te:It is requted that reflow soldering should be executed after heat of product go down to rmal.
Heat ristant line
(Used when heat ristant reliability tt is performed)
(2)Manual soldering
Manual soldering temperature 350 ℃ within 5 sec.
