Although it is possible to produce a capacitor of any capacitance value, manufacturers produce capacitors and resistors with standard values. These preferred values are based on a geometric series, commonly known as the E series. For a given series, the E value specifies the number of elements per decade.
This International Standard applies to capacitors for power electronics applications. The operating frequency of the systems in which these capacitors are used is usually up to 15 kHz, while the pulse frequencies may be up to 5 to 10 times the operating frequency. The document...
Selection and calibration of capacitors for use as Standards is a challenging task, especially since the accuracies required, depening on the application, can be very demanding for the test gear as well as for the secondary- and working-standards used.
Standardization of component values enables easier production of components in bulk. Moreover, standardization of capacitor and resistor values enables compatibility of components from different manufacturers. In addition to defining capacitance and resistance, the preferred number series provides recommended tolerances.
Unlike resistance, capacitor values are usually defined in two significant digits. It is, therefore, not common to apply the E48, E96, and E192 series and recommended tolerances. In most cases, capacitor manufacturers use tighter tolerances for these passive components.
The series capacitor units and banks are usually intended for high-voltage power systems. This standard is applicable to the complete voltage range. This standard does not apply to capacitors of the self-healing metallized dielectric type. The following capacitors, even if connected in series with a circuit, are excluded from this standard:
