Scope: This standard applies to Class 1 and Class 2 unsealed multilayer ceramic dielectric capacitors with a rated voltage generally not exceeding 200 V for electronic equipment. If necessary, higher voltages can be specified in detailed specifications. These capacitors have metallized soldering areas or strip terminals for direct installation on the substrate or printed circuit board of hybrid circuits. The purpose of this standard is to specify priority ratings and characteristics for this type of capacitor, select applicable quality assessment procedures, testing and measurement methods from GB 2693, and provide general characteristic requirements. The test severity and requirements specified in the detailed specifications should have the same or higher performance level as this standard. Because the reduced performance level is not allowed. The provisions contained in the following standards in the relevant documents constitute the provisions of this standard by reference in this standard. At the time of publication of this standard, all versions shown are valid. All standards will be revised, and parties using this standard should explore the possibility of using the latest versions of the following standards.
