Assessment level E>>SJ/T*******4
<<Detail specification for electronic components fixed

Assessment level E>>SJ/T*******4
3.Classify:
CC*1:Classâ… dielectric，Such as NPO(N),COG,Electrical
character is stability and not
change with the temperature time and voltage basically,Suit for
high frequency circuit
that must be high stability.
CT*1:Class II dielectric，Such as X7R(B), Electrical
character is stability and not change
with the temperature time and voltage rapidly,Suit for
Blocking,Coupling ,By-passing
and other circuits that the requirement to stability of capacitance
is not strict.
Classâ…¢ dielectric,Such as Y 5 V(Y),Z 5 U(Z),Having high
dielectric constant,It can be
used to produce capacitors with more larger capacitance, But the
stability of
capacitance is poorer than X7R,The capacitance and tanδ is
sensitive with the
temperature and voltage.
4.Test Conditions:
4.1:Standard Condition:If there are no specific prescribe,The test
will be done according to
standard condition(Temperature ****5 degree,Relative Humidity
****5%), But If there are any
problems subject to standard condition or there are some specific
requirements, Please
test according to 4.2
4.2:Fundamental Condition:Temperature is *0 degree;Relative
Humidity is ****0%;Atmospheric
pressure is *******0mbar.
5.Testing Method:
When the products will be tested, In order to avoid the error of
result, The capacitors must
be placed in the temperature that the capacitors be tested for *0
minutes and discharged
fully.
