DFDA Series Technical Data
1. Storage
The DFDA series film capacitors must be stored between
40 C to 100 C.
5. Voltage Derating for Pulse Waves
The voltage derating rate for pulse waves at a maximum
operating temperature of 85 C is shown in
Figure 3.
A
pulse wave and the formula for determining the sinusoidal
AC voltage (Ep-p) are shown in
Figure 4.
Refer to
Section 7
for sine wave values.

2. Operating Temperature
Generally, the operating temperature is the ambient tem-
perature; however, the operating temperature will be the
surface temperature of the capacitor if self-heating occurs
due to ripple current or a charge-discharge current, or if
surface heating is caused by other components.

3. Rated AC Voltage
If the DFDA series capacitors are used in an AC circuit, 50
to 60 Hz and within an operating temperature of 40 C to
85 C (including self-heating), the rated AC voltage must
not exceed the values shown in
Table 1.

4. AC and DC Voltage Derating
If the operating temperature of the DFDA series capacitors
exceeds 85 C, the applied voltage should be derated as
specified in
Figure 1
for DC or
Figure 2
for AC voltage. This
will prevent capacitor damage and reduce the failure rate.
Note: If the applied voltage contains both AC and DC, the
peak voltage must not exceed the rated voltage.
