Test Method
First, repeat the following temperature/time cycle 5
times :
lowest operating temperature T3˚C/30T3 min.
ordinary temperature/3 min. max.
highest operating temperature T3˚C/30T3 min.
ordinary temperature/3 min. max.
Next, repeat twice the successive cycles of immersion,
each cycle consisting of immersion in a fresh water at
65
W5
Y0
˚C for 15 min. and immersion in a saturated
aqueous solution of salt at 0T3˚C for 15 min.
The capacitor is then promptly washed in running
water, dried with a drying cloth, and allowed to sit at
room temperature for 24T2 hrs. (temperature
compensating type) or 48T4 hrs. (high dielectric type).
• Initial measurement for high dielectric constant type
The capacitors are heat treated for 1 hr. at
150

˚C, allowed to sit at room temperature for 48
T4 hrs., and given an initial measurement.

Strength
Termination not to be broken or loosened
As in the figure, fix the capacitor body, apply the force
gradually to each lead in the radial direction of the
capacitor until reaching 10N and then keep the force
applied for 10T1 sec.
F
Bending
Strength
Termination not to be broken or loosened
Each lead wire should be subjected to a force of 2.5N
and then bent 90˚ at the point of egress in one
direction. Each wire is then returned to the original
position and bent 90˚ in the opposite direction at the
rate of one bend per 2 to 3 sec.

Within the specified tolerance
The capacitor is soldered securely to a supporting
terminal and a 10 to 55Hz vibration of 1.5mm peak-
peak amplitude is applied for 6 hrs. total, 2 hrs. in each
mutually perpendicular direction. Allow 1 min. to cycle
the frequency from 10Hz to 55Hz and the converse.

12 Solderability of Leads
Lead wire should be soldered with uniform coating on the axial
direction over 3/4 of the circumferential direction.
The terminal of a capacitor is dipped into a 25% ethanol
(JIS-K-8101) solution of rosin (JIS-K-5902) and
then into molten solder for 2T0.5 sec. In both cases the
depth of dipping is up to about 1.5mm to 2mm from the
terminal body.
Temp. of solder : 245T5˚C Lead Free Solder (Sn-3.0Ag-0.5Cu)
Temp. of solder : 235T5˚C H60A or H63A Eutectic Solder
