MOUNTING
Normal Use
The capacitors are designed for mounting on printed-circuit boards. The capacitors packed in bandoliers are designed for
mounting in printed-circuit boards by means of automatic insertion machines.
For detailed tape specifications refer to packaging information www.vishay.com/docs?28139
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 space for length (Imax.), width (wmax.) and height (hmax.) of film capacitors to take in account on the printed-circuit
board is shown in the drawings.
• For products with pitch 15 mm, w = l = 0.3 mm; h = 0.1 mm
Eccentricity defined as in drawing. The maximum eccentricity is smaller than or equal to the lead diameter of the product
concerned.

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 ambient temperature.
The power dissipation can be calculated according type detail specification “HQN-384-01/101: Technical Information Film
Capacitors”.
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 as in:
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.
For capacitors connected in parallel, normally the proof voltage and possibly the rated voltage must be reduced. For information
depending of the capacitance value and the number of parallel connections contact: dc-film@vishay.com
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 22 x URAC to avoid the ionization inception level
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 URDC and
divided by the applied voltage.
For all other pulses following equation must be fulfilled:
T
2
dU
dt
dU
2 x
------- x dt URDC x -------
dt
rated
0
T is the pulse duration.
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).

C = 330 nF - 63 V used for the voltage signal shown in next drawing.
UP-P = 40 V; UP = 35 V; T1 = 100 μs; T2 = 200 μs
The ambient temperature is 35 °C
Checking conditions:
1. The peak voltage UP = 35 V is lower than 63 VDC
2. The peak-to-peak voltage 40 V is lower than 22 x 40 VAC = 113 UP-P
3. The voltage pulse slope (dU/dt) = 40 V/100 μs = 0.4 V/μs
This is lower than 60 V/μs (see specific reference data for each version)
4. The dissipated power is 16.2 mW as calculated with fourier terms
The temperature rise for wmax. = 3.5 mm and pitch = 5 mm will be 16.2 mW/5.0 mW/°C = 3.24 °C
This is lower than 15 °C temperature rise at 35 °C, according figure “Max. allowed component temperature rise”
