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/doc?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 capacitors shall be mechanically fixed by the leads
• For larger pitches the capacitors shall be mounted in the same way and the body clamped in addition
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 x l = 0.3 mm and h = 0.1 mm
• For products with 15 mm < pitch 27.5 mm, w x l = 0.5 mm and h = 0.1 mm
• For products with pitch = 37.5 mm, w x l = 0.7 mm and h = 0.5 mm
Eccentricity defined as in drawing. The maximum eccentricity is smaller than or equal to the lead diameter of the product
concerned.

SOLDERING CONDITIONS
For general soldering conditions and wave soldering profile, we refer to the application note:
“Soldering Guideline for Film Capacitors”: www.vishay.com/doc?28171
Storage Temperature
Tstg = -25 °C to +35 °C with RH maximum 75 % without condensation
Ratings and Characteristics Reference Conditions
Unless otherwise specified, all electrical values apply to an ambient free air 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 %.

APPLICATION NOTES
• For X2 electromagnetic interference suppression in standard across the line applications (50 Hz / 60 Hz) with a maximum
mains voltage of 310 VAC.
• For series impedance applications we refer to application note www.vishay.com/doc?28153
• 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: rfi@vishay.com
• These capacitors are not intended for continuous pulse applications. For these situations, capacitors of the AC and pulse
programs must be used.
• The maximum ambient temperature must not exceed 110 °C (125 °C for less than 1000 h) for C 470 nF and 110 °C for
C > 470 nF.
• Rated voltage pulse slope:
if the pulse voltage is lower than the rated voltage, the values of the specific reference data can be multiplied by 435 VDC and
divided by the applied voltage.
