GENERAL INFORMATION
TECHNICAL TERMS EXPLANATION
Rated capacitance
Capacitance referred to 1 kHz, 20
±
1°C, 65
±
2% of relative humidity and 96 ±10 kPa.
In case of doubt please refer to IEC 60068-1, sub-clause 5.2.
Capacitance tolerance
Admitted capacitance deviation from the rated capacitance.
Rated temperature (T
R
)
The maximum ambient temperature surrounding the capacitor or hottest contact point (e.g.: tracks), whichever is
higher, at which the rated voltage, Vdc or Vac at 50 Hz, may be continuously applied.
Rated voltage (V
R
)
The maximum direct voltage or the maximum r.m.s. alternating voltage (50Hz) or the peak value of a pulse voltage
which may be continuously applied to a capacitor at any temperature between the lower category temperature
and the rated temperature.
Climatic category
The climatic category which the capacitor belongs to is expressed in numbers (standard IEC 60068-1:
e.g.: 25/125/21).
The first number represents the lower category temperature (e.g.: -25°C); the second number the upper category
temperature (e.g.: +125°C) and the third number represents the number of days relevant to the damp heat test
(e.g.: 21 days).
Dissipation factor (tg
δ
)
The dissipation factor is the ratio between the resistive and the reactive part of the impedance of the capacitor
submitted to a sinusoidal voltage of specified frequency.
Insulation resistance (Ir)
The insulation resistance is the ratio between an applied D.C. voltage and the resulting leakage current after a
minute of charge. It is expressed in MΩ.
APPLICATION NOTES - SAFETY CONDITIONS
1. Across-the-line and interference suppression applications
1.1 When a capacitor is used for this type of application it may be subject to a mains voltage on a
permanent basis and to surges caused, for example, by lightning, power commutations etc.
In these working conditions the capacitor must be a \component with a safety margin able to satisfy
