SPECIFICATION
3. 2
Vibration
resistance
Capacitance : no unsteady .
Appearance : no abnormal .
Capacitance change :
within ± 5% of initial measured
value .
The frequancy of the vibration shall vary uniformly
within the range 10 to 55 Hz with the amplitude of
1.5 mm , completing the cycle in the internal of one
minute .
The capacitor shall be securely mounted by its leads
with hold the body of capacitor .
The capacitor shall be vibrated in three mutually
perpendicular directions for a period of 2 hours in
each direction .
3. 3
Solderability
The leads are dipped in the solder bath of Sn
at 260 ± 5 ℃ for 2 ± 0.5 seconds . The dipping
depth should be set at 1.5 ~ 2.0 mm .
The solder alloy shall cover the
95% or more of the dipped lead's
area .
4. Reliability
NO.
