• Metallized polyester
• According to CECC 30401-042, IEC 60384-2, DIN 44122
NEW OPTIMIZED SERIES IN SMALLER DIMENSIONS
There are now many parts in the MMK series in smaller sizes than before. The capacitance
range has also been extended. These parts are marked with * in the article table. The size
codes for the bigger old parts are shown in the article table next to the new article code.
Table with all size codes on page 18.

TYPICAL APPLICATIONS
Bypassing, signal coupling. General
purpose for highest reliability.
CONSTRUCTION
Metallized polyester film capacitor. Radial
leads of tinned wire are electrically welded
to the contact metal layer on the ends of
the capacitor winding. Encapsulation in
self-extinguishing material meeting the
requirements of UL 94V-0.

ORDERING INFORMATION
See article table and pages 18 to 23 for
options and article code construction.
The standard quantity/reel is for 360 mm
reel. If 500 mm reel is required, it must be
specified when ordering and the quantity is
2 x the given quantity.
