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.

Step

Temperature(˚C)

a

25± 2

b

Lower temperature± 3˚C

c

25± 2

d

Upper Temperature± 2˚C

e

(1) Class I

Temperature Coefficient shall be calculated from the formula as

below

Temp, Coefficient =

C2-C1

C1

C1: Capacitance at step c

C2: Capacitance at 125˚C

T: 100˚C (=125˚C-25˚C)

(2) Class II

Capacitance Change shall be calculated from the formula as

below

C =

C2-C1

C1

x 100%

C1: Capacitance at step c

C2: Capacitance at step b or d

Class I:

C/C: ± 30ppm

Class II:

X7R:

C/C: ±15%
