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 TO 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 mm the 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

STORAGE TEMPERATURE

• Storage temperature: T

= - 25 °C to + 40 °C with RH maximum 80 % without condensation

RATINGS AND CHARACTERISTICS REFERENCE CONDITIONS

Unless otherwise specified, all electrical values apply to an ambient free temperature of 23 ± 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 ± 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)

MEASURING THE COMPONENT TEMPERATURE

A thermocouple must be attached to the capacitor body as in:

Thermocouple

The temperature is measured in unloaded (T
The temperature rise is given by ΔT = T

c

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 (U

2. The peak-to-peak voltage (U

3. The voltage peak 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
divided by the applied voltage.

For all other pulses following equation must be fulfilled:

) shall not be greater than the rated DC voltage (U

P

) shall not be greater than the maximum (U

P-P

) and maximum loaded condition (TC).

4. The maximum component surface temperature rise must be lower than the limits (see graph max. allowed component
temperature rise).

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 the table: “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 the following conditions are fulfilled in any case (spikes and
surge voltages from the mains included).
