MOUNTING
Normal Use
The capacitors are designed for mounting on printed-circuit boards. The capacitors packed in bandoliers are designed for
mounting on printed-circuit boards by means of automatic insertion machines

Specific Method of Mounting of Withstand Vibration and Shock
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.
• For pitches ≤ 15 mmthe capacitors shall be mechanically fixed by the leads
• For larger pitches the capacitors shall be mounted in the same way and the body clamped
Space Requirements on Printed-Circuit Board
The maximum length and width of film capacitors is shown in the drawing:
• Eccentricity as in drawing. The maximum eccentricity is smaller than or equal to the lead diameter of the product concerned
• Product height with seating plane as given by “IEC 60717” as reference: h

Ratings and Characteristics Reference Conditions
Unless otherwise specified, all electrical values apply to an ambient free temperature of 23 °C ± 1 °C, an atmospheric pressure
of 86 kPa to 106 kPa and a relative humidity of 50 % ± 2 %.
For reference testing, a conditioning period shall be applied over 96 h ± 4 h by heating the products in a circulating air oven at
the rated temperature and a relative humidity not exceeding 20 %.

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 type detail specification “HQN-384-01/101: Technical Information Film
Capacitors” with the typical tgd of the curves.
The component temperature rise (ΔT) can be measured (see section “Measuring the component temperature” for more details)
or calculated by ΔT = P/G:
ΔT = Component temperature rise (°C)
• P = Power dissipation of the component (mW)
• G = Heat conductivity of the component (mW/°C)

APPLICATION NOTE AND LIMITING CONDITIONS
To select the capacitor for a certain application, the following conditions must be checked:
1. The peak voltage (U
2. The peak-to-peak voltage (U
3. The maximum component surface temperature rise must be lower than the limits
4. The maximum application temperature must be lower than 105 °C
5. There is no limit for the voltage pulse slope in the application
