PROCEDURE
REQUIREMENTS
Capacitance shall be measured by the steps shown in the following
table.
The capacitance change should be measured after 5 min at each
specified temperature stage.
Class1: Δ C/C: ± 30ppm
Class2: X7R: Δ C/C: ± 15%
Y5V: Δ C/C: 22~-82%
Step
Temperature(℃)
a
25± 2
b
Lower temperature± 3℃
c
25± 2
d
Upper Temperature± 2℃
e
25± 2
(1) Class I
Temperature Coefficient shall be calculated from the formula as
below
Temp, Coefficient = C2 - C1 106 [ppm/℃]
C1 xΔT
C1: Capacitance at step c
C2: Capacitance at 125℃
∆T: 100℃(=125℃-25℃)
(2) Class II
Capacitance Change shall be calculated from the formula as below
∆C = C2 - C1 x 100%
C1
C1: Capacitance at step c
C2: Capacitance at step b or d
