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-165
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 Stripped wires are immersed in rosin for
5 seconds and then immersed in solder bath
of 270 ±5°C for 3 ±1 seconds.
soldering heat resistance Stripped wires are immersed up to 1.5mm from
buzzer’s body in solder bath of 300 ±5°C for
3 ±0.5 seconds or 260 ±5°C for 10 ±1 seconds.
lead wire pull strength The pull force shall be applied to lead wire:
Horizontal 3.0N
Vertical 2.0N
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.
bottom covering pull force The pull force of 3.0N shall be applied to
bottom covering on the vertical direction.
evaluation standard
90% min. of the lead terminals
will be wet with solder
(except the edge of the terminal).
No interference in operation.
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.
No damage or cutting off.
