5. Specification and test methods
No. Item Specification Test method
1 Appearance and dimensions No marked defect on appearance
form and dimensions.
Please refer to [Part number list].
The capacitor should be inspected by naked eyes
for visible evidence of defect.
Dimensions should be measured with slide calipers.
2 Marking To be easily legible. The capacitor should be inspected by naked eyes.
3 Dielectric
strength
Between lead
wires
No failure. The capacitor should not be damaged when DC
voltage of 200% of the rated voltage are applied
between the lead wires for 1 to 5 s.
(Charge/Discharge current50mA.)
Body
insulation
No failure. The capacitor is placed in the container with metal
balls of diameter 1mm so that each lead wire,
shortcircuited, is kept about 2mm
off the balls as shown in the figure,
and DC voltage of 1.3kV is
applied for 1 to 5 s between
capacitor lead wires and
small metals.
(Charge/Discharge current50mA.)
4 Insulation
Resistance (I.R.)
Between lead
wires
10000M min.
The insulation resistance should be measured with
DC50050V within 605 s of charging.
5 Capacitance Within specified tolerance.
The capacitance should be measured at 20C with
10.2kHz (Char. SL : 10.2MHz) and
AC5V(r.m.s.) max..
6 Q Char. SL :
400+20C*²min. (30pF under)
1000 min. (30pF min.)
The dissipation factor and Q should be measured
at 20C with 10.2kHz (Char. SL : 10.2MHz) and
AC5V(r.m.s.) max..
Dissipation Factor (D.F.) Char. B,E : 2.5% max.
7 Temperature characteristic
Char. SL : +350 to - 1000ppm/C
(Temp. range: +20 to 85C)
Char. B : Within 10 %
Char. E : Within +20/-55%
The capacitance measurement should be made at
each step specified in Table.
Pre-treatment : Capacitor should be stored at 852C for 1 h, then placed at *¹room
condition for 242 h before initial measurements. (Char. B,E)
8
Strength of lead Pull
Lead wire should not cut off.
Capacitor should not be broken.
As shown in the figure at right, fix the body
of the capacitor and apply a tensile weight
gradually to each lead wire in the radial
direction of the capacitor up to 10N
and keep it for 101 s.
Bending Each lead wire should be subjected to 5N of weight
and bent 90 at the point of egress, in one direction,
then returned to its original position and bent 90 in
the opposite direction at the rate of one bend in 2 to
3 s.
9 Vibration
resistance
Appearance No marked defect. The capacitor should be firmly soldered to the
supporting lead wire and vibrated at a frequency
range of 10 to 55Hz, 1.5mm in total amplitude, with
about a 1min rate of vibration change from 10Hz
to 55Hz and back to 10Hz. Apply for a total of 6 h;
2 h each in 3 mutually perpendicular directions.
Capacitance Within specified tolerance.
Q Char. SL :
400+20C*²min. (30pF under)
1000 min. (30pF min.)
D.F. Char. B,E : 2.5% max.
10 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 20.5 s. In both cases the depth of
dipping is up to about 1.5 to 2mm from the root of
lead wires.
