CONSTRUCTION
Description
SPECIFIC METHOD OF MOUNTING TO WITHSTAND VIBRATION
AND SHOCK TEST
In order to withstand vibration and shock tests, it must be
ensured that the stand-off pips are in good contact with the
printed-circuit board.
• Low-inductive wound cell of metallized polyethylene
terephthalate (PETP) film, potted with epoxy resin in a
flame-retardant case
• Radial leads
SPACE REQUIREMENTS ON PRINTED-CIRCUIT BOARD
• Small stand-off pips allow removal of solder flux etc.
during cleaning of the printed-circuit board.
The maximum length and width of film capacitors is shown
in Fig.8:
• Eccentricity see Fig.8. The maximum eccentricity is
smaller than or equal to the wire diameter of the product
concerned.
• Product height with seating plane as given by
“IEC 60717” as reference: hmax ≤ h + 0.3 mm.

RATINGS AND CHARACTERISTICS REFERENCE
CONDITIONS
The capacitors are designed for mounting on printed-circuit
boards. The capacitors packed in bandoliers are designed
for mounting on printed-circuit boards by automatic
insertion machines.
For detailed tape specifications refer to this handbook,

Power dissipation and maximum component temperature rise
The power dissipation must be limited in order not to exceed the maximum allowed component temperature rise as a
function of the free air ambient temperature.
The power dissipation can be calculated according chapter “Introduction”, section “Maximum power dissipation”.
The component temperature rise (∆T) can be measured (see section “Measuring the component temperature” for more
details) or calculated by ∆T = P ⁄ G :
• ∆T = component temperature rise (°C).
• P = power dissipation of the component (mW).
• G = heat conductivity of the component (mW/°C).

Measuring the component temperature
A thermocouple must be attached to the capacitor body; see Fig.24.

thermocouple
CBA758
Fig.24 Mounting the thermocouple.
The temperature is measured in unloaded (Tamb) and maximum loaded condition
(Tc).
The temperature rise is given by: ∆T = Tc – Tamb
.
To avoid radiation or convection, the capacitor should be tested in a wind-free
box.

Application note and limiting conditions
These capacitors are not suitable for mains applications as across-the-line capacitors without additional protection, as
described hereunder. These mains applications are strictly regulated in safety standards and therefore electromagnetic
interference suppression capacitors conforming the standards must be used.
To select the capacitor for a certain application, the following conditions must be checked:
1. The peak voltage (Up) shall not be greater than the rated DC voltage (URdc).
2. The peak-to-peak voltage (Up-p) shall not be greater than the maximum Up-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 URdc and divided by the applied voltage.
For all other pulses following equation must be fulfilled:
T
2
dU
dt

2 × ------- × dt < URdc × -------
∫

rated
T is the pulse duration.
The rated voltage pulse slope is valid for ambient temperatures up to 85 °C. For higher temperatures a derating factor
of 3% per K shall be applied.
4. The maximum component surface temperature rise must be lower than the limits in Fig.23.
5. Since in circuits used at voltages over 280 V peak-to-peak the risk for an intrinsically active flammability after a
capacitor breakdown (short circuit) increases, it is recommended that the power to the component is limited to
100 times the values mentioned in Table 1 “Heat conductivity”.
6. When using these capacitors as across-the-line capacitor in the input filter for mains applications or as series connected
with an impedance to the mains the applicant must guarantee that following conditions are fulfilled in any case (spikes
and surge voltages from the mains included).
