9 Robustness of
terminations
Tensile Lead wire should not cut off.
Capacitor should not be broken.
Fix the body of capacitor, a tensile weight
gradually to each lead wire in the radial direction of
capacitor up to 10N and keep it for 101 s.
Bending With the termination in its normal position, the
capacitor is held by its body in such a manner that
the axis of the termination is vertical; a mass
applying a force of 5N is then suspended from the
end of the termination.
The body of the capacitor is then inclined,
within a period of 2 to 3 s, through an angle of
approximately 90 in the vertical plane and then
returned to its initial position over the same period
of time; this operation constitutes one bend.
One bend immediately followed by a second bend
in the opposite direction.
10 Vibration
resistance
Appearance No marked defect. The capacitor should be firmly soldered to the
supporting lead wire and vibration which is 10 to
55Hz in the vibration frequency range,1.5mm in
total amplitude, and about 1min in the rate of
vibration change from 10Hz to 55Hz and back to
10Hz is applied for a total of 6 h; 2 h each in
3 mutually perpendicular directions.
Capacitance Within the specified tolerance.
D.F. 2.5% max.
11 Solderability of leads Lead wire should be soldered
With uniformly coated on the
axial direction over 3/4 of the
circumferential direction.
The lead wire of a capacitor should be dipped into a
ethanol solution of 25wt% rosin and then into
molten solder for 20.5 s. In both cases the depth of
dipping is up to about 1.5 to 2.0mm from the root of
lead wires.
Temp. of solder :
245±5°C Lead Free Solder (Sn-3Ag-0.5Cu)

immersed solder of 260+0/-5°C up to 1.5 to 2.0mm
from the root of terminal for 7.5+0/-1 s.
