ENVIRONMENT TEST
item test condition
high temp. test After being placed in a chamber at +95°C for
240 hours.
low temp. test After being placed in a chamber at -40°C for
240 hours.
humidity test After being placed in a chamber at +40°C and
90±5% relative humidity for 240 hours.
temp. cycle test The part shall be subjected to 5 cycles. One
cycle will consist of:
PART NUMBER: CPE-267
evaluation standard
The buzzer will be measured after
being placed at +25°C for 4
hours. The value of the
oscillation frequency/current
consumption should be ±10%
compared to the initial
measurements. The SPL should
be within ±10dB compared to the
initial measurements.
MECHANICAL CHARACTERISTICS
item test condition
solderability Lead terminals are immersed in rosin for
(connector excepted) 5 seconds and then immersed in solder bath
of 270 ±5°C for 3 ±0.5 seconds.
lead wire pull strength The pull force shall be applied to double lead
wire:
Horizontal 3.0N (0.306 kg) for 30 seconds
Vertical 2.0N (0.204 kg) for 30 seconds
vibration The buzzer shall 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.
drop test 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.
evaluation standard
90% min. of the lead terminals
will be wet with solder
(except the edge of the terminal).
No damage or cutting off.
The value of oscillation
frequency/current consumption
should be ±10% of the initial
measurements. The SPL should
be within ±10dB compared with
the initial measurement.
