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 specification 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
Space Requirements on Printed Circuit Board
The maximum space for length (I
max.
), width (w
max.
) and height (h
max.
) of film capacitors to take in account on the printed-circuit
board is shown in the drawings.
• For products with pitch ≤ 15 mm, Δw = Δl = 0.3 mm; Δh = 0.1 mm
• For products with 15 mm < pitch ≤ 27.5 mm, Δw = Δl = 0.5 mm; Δh = 0.1 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 Guidelines for Film Capacitors”: www.vishay.com/doc?28171
Storage Temperature
• Storage temperature: T
stg
= - 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 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 %
.
