2.4 FREQUENCY DEPENDENCE OF
DISSIPATION FACTOR
Dissipation factor increased with frequency. The variation
pattern is different for different dielectrics. The typical
variation pattern for different dielectrics are shown in fig.
2.4A, 2.4B and 2.4C.
2.5 TEMPERATURE DEPENDENCE OF INSULATION
RESISTANCE
The insulation resistance of the dielectric varies with
temperature. The variation pattern is different fro different
dielectric films. The typical variation pattern for different
dielectrics are shown in figure 2.5A, 2.5B and 2.5C.
ELECTRICAL - AC APPLICATIONS
When a capacitor is connected to alternating voltage its
electrodes are alternately charged positive and negative.
The charge alternates with a rhythm of double the
frequency of the alternating voltage. Thus there is
alternating current flowing in the leads of the capacitor.
3.1 ACROSS THE LINE APPLICATIONS
In this application the capacitor is connected between the
lines, ie, between the main phase and neutral line
terminals. In this type of application, failure of capacitor
due to short circuit will not result in an electric shock. The
capacitors rated for normal across the line applications
are termed class-X2 capacitors.
3.2 BETWEEN LINE AND GROUND APPLICATIONS
In this type of application the capacitors are connected
between the line and the ground, ie, between the phase
terminal and the body. In this application, failure of the
capacitor due to short circuit could possibly expose
somebody touching the appliance to an electric shock.
The capacitors rated for this application are termed class-
Y capacitors.
MECHANICAL CHARACTERISTICS
4.1 RESISTANCE TO SOLVENTS
The encapsulation technics adopted in the manufacture of
plastic film capacitors ensure resistance to a wide range
of solvents and cleaning liquids. The epoxy end sealed
boxed capacitors can stand Trichloro trifluorethane,
Methanol, Ethanol, Isopropanol and Aqueous cleaning
solvents.
4.2 SOLDERABILITY
A minimum of 3/4 of the circumferential surface of the
terminations will be covered with new solder when dipped
in molten solder bath at 230 °C for 2 ±1 sec. after
immersing in methanol - rosin solution at room
temperature for 5 to 10 seconds.

4.3 TERMINAL STRENGTH
The leads are made of tinned copper wire. The terminals are capable of withstanding an axial load of
2.25 Kgs(5 lbs).
ENVIRONMENTAL
RESISTANCE TO HUMIDITY
The capacitor samples will be exposed to 93 ±2 °C for 56 days at 40 ±2 °C. After the test the
capacitance change shall be within 3% of the original value, The insulation resistance shall be within
50% of the initial limits and the dissipation factor shall remain within the initial specifications.
