1.Scope：

This specification applies to CC4(CT4) Multilayer Ceramic capacitors produced by our company for use in electronic equipment。

  2.Standard：

   《Detail specification for electronic components fixed ceramic dielectric capacitors CC4 Assessment level E》 SJ/T10569-94

《Detail specification for electronic components fixed ceramic dielectric capacitors CT4 Assessment level E》 SJ/T10570-94

  3.Classify：

    CC41：ClassⅠdielectric，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。

CT41：ClassⅡ 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。

              ClassⅢ dielectric，Such as Y5V（Y）、Z5U（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 15-35℃;Relative Humidity 45-75%), 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 20℃;Relative Humidity is 60-70%;Atmospheric pressure is 800-1060mbar。

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 30 minutes and discharged fully.
