PART NUMBER: CSS-J4D20
DESCRIPTION: magnetic buzzer
page 2 of 5
TYPICAL FREQUENCY RESPONSE CURVE
Lead terminals are immersed in solder bath
of 270 ±5°C for 3 ±1 seconds.
soldering heat resistance
The buzzer follows the reflow temperature
curve to test its reflow thermo stability.
terminal mechanical strength
Lead pads will be soldered onto the PCB, the
force of 9.8N (1.0kg) is applied behind the part
for 10 seconds.
The buzzer will be measured after applying
a vibration amplitude of 1.5 mm with 10 to
55 Hz band of vibration frequency to each of
the 3 perpendicular directions for 2 hours.
The part will be dropped from a height of
75 cm onto a 40 mm thick wooden board 3
times in 3 axes (X, Y, Z) for a total of 9 drops.
95% of the lead pad surfaces
must be covered with fresh solder
No interference in operation.
No damage or cutting off.
After the test, the part will meet
specifications without any
damage to its appearance. The
SPL should be within ±10dB
