Visual inspection
Using calipers and micrometers
No failure should be observed when voltage in the table is
applied between the terminations for 60T1 sec., provided the
charge/discharge current is less than 50mA.

10 impulses of alternating polarity are subjected.
(5 impulses for each polarity)
The interval between impulses is 60 sec.
Applied Pulse: 1.2/50µs
Applied Voltage: 2.5kVo-p
The insulation resistance should be measured with DC500T50V
and within 60T5 sec. of charging.
The capacitance/Q/D.F. should be measured at a frequency of
1T0.2kHz (SL char.: 1T0.2MHz) and a voltage of
AC1T0.2V (r.m.s.)
The capacitance measurement should be made at each step
specified in the Table.

The capacitance should be measured at even 85D between step
3 and step 4.
#Pretreatment for X7R char.
Perform a heat treatment at 150Y ^W10 ⁰D for 60T5 min. and then
let sit for 24T2 hrs. at room condition.*¹
As in Fig., discharge is made 50 times at 5 sec. intervals from
the capacitor (Cd) charged at DC voltage of specified.

Adhesive Strength
of Termination
No removal of the terminations or other defect should occur.

Solder the capacitor to the testing jig (glass epoxy board) shown
in Fig. 1.
Then apply 10N force in the direction of the arrow. The soldering
should be done using the reflow method and should be
conducted with care so that the soldering is uniform and free of
defects such as heat shock.

*1 "Room condition" Temperature: 15 to 35D, Relative humidity: 45 to 75%, Atmospheric pressure: 86 to 106kPa
*2 "C" expresses nominal capacitance value (pF).
