• Metallized polyester
• According to CECC 30401-042, IEC 60384-2, DIN 44122
NEW OP TIMIZED S ERIES IN S MALLER DIMENS IONS
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.

TYP ICAL AP P LICATIONS
CONS TRUCTION
Bypassing, signal coupling. General
purpose for highest reliability.
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.
