BC Components Product specification
Metallized polypropylene filter capacitors MKP 416 to 420
CONSTRUCTION
Description
•Low-inductive wound cell of metallized polypropylene
(PP) film, potted with epoxy resin in a flame-retardant
case
•Radial leads, solder-coated
•Solder-plated copper-clad steel wire to ensure good
resistance to soldering heat
•Small stand-off pips allow removal of solder flux etc.
during cleaning of the printed-circuit board.
Mounting
NORMAL USE
The capacitors are designed for printed-circuit board
applications. The capacitors packed in bandoliers are
designed for mounting on printed-circuit boards by means
of automatic insertion machines. For detailed
specifications refer to this handbook, chapter
“Packaging
information”
.

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.
The capacitors shall be mechanically fixed by the leads.
SPACE REQUIREMENTS ON PRINTED-CIRCUIT BOARD
The maximum length and width of film capacitors is shown
in Fig.11:
•Eccentricity as in Fig.11. 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: hmax ≤h+0.3 mm.
Storage temperature
•Storage temperature: Tstg =−25 to +40 °C with RH
maximum 80% without condensation.
RATINGS AND CHARACTERISTICS REFERENCE
CONDITIONS
Unless otherwise specified, all electrical values apply at an
ambient free air temperature of 23 ±1°C, an atmospheric
pressure of 86 to 106 kPa and a relative humidity of
50 ±2%.
For reference testing, a conditioning period shall be
applied over 96 ±4 hours by heating the products in a
circulating air oven at the rated temperature and a relative
humidity not exceeding 20%.
