©KEMET Electronics Corporation, P.O. Box 5928, Greenville, S.C. 29606, (864) 963-6300CERAMIC CHIP CAPACITORS For Class II and III dielectrics (including X7R,X5R, Z5U & Y5V), the first symbol indicates the lower limit of the operating temperature range, the second indicates the upper limit of the operating

temperature range, and the third indicates the maximum capacitance change allowed over the operating temperature range. EIA type designa-tion codes for Class II and III dielectrics are shown in Table 2. Capacitance Tolerance:

See tables on pages 73-76.

Capacitance:

Within specified tolerance when measured per Table 3.The standard unit of capacitance is the farad.For practical capacitors, capacitance is usually expressed in microfarads (10 -6farad), nanofarads -9farad), or picofarads (10 -12farad). Standard measurement conditions are listed in Table 3 -Specified Electrical Limits.

Like all other practical capacitors, multilayer

ceramic capacitors also have resistance and

inductance. A simplified schematic for the single frequency equivalent circuit is shown in Figure 1.At high frequency more complex models apply -see KEMET SPICE models at http://m.wendangku.net/doc/0cc1887e8e9951e79b8927bf.html for details.Table 1 – EIA Temperature Characteristic Codes for Class I Dielectrics
