D.TESTING METHOD
Standard Measurement conditi*
Temperature:25&plu*n;2℃ Humidity:45-65%
Acoustic Characteristics:
The oscillation frequency, current c*umption and sound pressure are measured by the measuring instruments shown below
In the measuring test, buzzer is placed as follows:
E. Typical Frequency Resp*e Curve
F. Recommend Driving Circuit
The base current Ib should high enough so that it saturates the collector curre*f the transistor with the CB load.
G. Soldering Condition
(1)Recommendable reflow soldering condition is as follows
(Reflow soldering is twice)
Note:It is requested that reflow soldering should be executed after heat of product goes dow*normal.
Heat resistant line
(Used when heat resista*eliability test is performed)
(2)Manual soldering
Manual soldering temperature 350 ℃ within 5 sec.
