Polypropylene film foil capacitors
KP 460 to 464
Measuring the component temperature
A thermocouple must be attached to the capacitor body as
in Fig.27.
The temperature is measured in unloaded (T
amb
) and
maximum loaded condition (T
c
).
The temperature rise is given by
.
To avoid radiation or convection, the capacitor should be
tested in a wind-free box.

Application note and limiting conditions
To select the capacitor for a certain application, the
following conditions must be checked:
1.
The peak voltage (U
p
) shall not be greater than the rated
DC voltage (U
Rdc
).
2.
The peak-to-peak voltage (U
p-p
) shall not be greater than
the maximum U
p-p
to avoid the ionisation inception
level.
3.
The voltage pulse slope (dU/dt) shall not exceed the
rated voltage pulse slope in an RC-circuit at rated
voltage and without ringing. If the pulse voltage is lower
than the rated DC voltage, the rated voltage pulse slope
may be multiplied by U
Rdc
and divided by the applied
voltage.
For all other pulses following equation must be fulfilled:
T is the pulse duration.
The maximum component surface temperature rise
must be lower than the limits in Fig.26.
The maximum component surface temperature must be
lower than 100
°
C.
The capacitance drift is influenced by the soldering
conditions (see section
“
Soldering conditions
”
for more
details).
