Description :
Class 1 ceramic capacitors (NPO) meet NF C 83131 (CECC 30600) standard requirements applicable to class and climatic category specifications. These capacitors are mainly intended for applications requiring low losses and high capacitance stability, and circuits where a defined temperature coefficient is required. They are not designed for currents above 1 A, nor for a reactive power higher than 200 VAR.

Class 2 molded ceramic capacitors meet NF C 83132 (CECC 30700) standard requirements applicable to capacitance/temperature and climatic category specifications. These capacitors are suited to applications where low losses and high
capacitance stability are not critical. They are not designed for currents above 1 A, nor for reactive powers higher than 200 VAR.
As for multilayer chips, the dielectric composition may contain a flux additive (bismuth in particular) or may be a flux free ceramic.
That is why class 2 molded ceramic capacitors are differentiated in flux and flux free dielectric series, suffix “A” being added to model designation to identify flux free ceramic capacitors.
