The rated voltage is defined as the maximum voltage which may be
applied continuously to the capacitor. When AC voltage is
superimposed on DC voltage, VP-P or VO-P, whichever is larger,
should be maintained within the rated voltage range.
No defects or abnormalities
Within the specified dimensions
Using calipers or Microscope. (GRM02 size is based on Microscope)
No defects or abnormalities
No failure should be observed when 300% of the rated voltage (C
to 7U and 1X) or 250% of the rated voltage (R6, R7,C8,E4 and F5) is
applied between the terminations for 1 to 5 seconds, provided the
charge/ discharge current is less than 50mA.
More than 10,000Mor 500∙F

The insulation resistance should be measured with a DC voltage not
exceeding the rated voltage at 25C and 75%RH max. and within 2
minutes of charging.
Within the specified tolerance
The capacitance/Q/D.F. should be measured at 25C at the
frequency and voltage shown in the table.

The capacitance change should be measured after 5 min. at
each specified temperature stage.
(1)Temperature Compensating Type
The temperature coefficient is determind using the capacitance
measured in step 3 as a reference. When cycling the temperature
sequentially from step1 through 5 (C+25C to +125C , other
temp. coeffs.:+25C to +85C ) the capacitance should be within
the specified tolerance for the temperature coefficient and
capacitance change as Table A-1. The capacitance drift is
caluculated by dividing the differences betweeen the maximum and
minimum measured values in the step 1,3 and 5 by the cap value in
step 3.
(2) High Dielectric Constant Type
The ranges of capacitance change compared with the 25C value
over the temperature ranges shown in the table should be within
the specified ranges.
Initial measurement for high dielectric constant type.
Perform a heat treatment at 150+0/-10Cfor one hour
and then set for 24±2 hours at room temperature.
Perform the initial measurement.
Within the specified tolerance.

Adhesive Strength of
Termination
No removal of the terminations or other defect should occur.
Solder the capacitor to the test jig (glass epoxy board) shown in Fig.1
using a eutectic solder. Then apply *10N force in parallel with the test
jig for 10±1sec.
The soldering should be done either with an iron or using the reflow
method and should be conducted with care so that the soldering is
uniform and free of defects such as heat shock
