(Note 1) These Specifications and Test Methods indicate typical inspection.
The capacitance change should be measured after 5 min. at
each specified temp. stage.
(1)Temperature Compensating Type
The temperature coefficient is determined using the
capacitance measured in step 3 as a reference.
When cycling the temperature sequentially from steps 1
through 5 (5C: +25 to +125 C/ C: +20 to +125 C: other temp.
coeffs.: +25 to +85 C/+20 to +85 C) the capacitance should be
within the specified tolerance for the temperature coefficient
and capacitance change as in Table A-1.
The capacitance drift is calculated by dividing the differences
between the maximum and minimum measured values in the
steps 1, 3 and 5 by the cap. value in step 3.
(2) High Dielectric Constant Type
The ranges of capacitance change compared with the
Reference Temperature value over the temperature ranges
shown in the table should be within the specified ranges.*
When applying voltage, the capacitance change should be
measured after 1 more min. with applying voltage in
equilibration of each temp. stage.
Solder the capacitor to the test jig (glass epoxy board) shown in
Fig. 1a using a eutectic solder. Then apply 10N* force in
parallel with the test jig for 10 1 sec.
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.
