Marking of WIMA Capacitors
SMD Capacitors
Marking of WIMA SMD capacitors was gradually ceased as of July 2003. Identification is possible by the labelling of
packages and delivery notes respectively.

Through-Hole Capacitors
In general, WIMA
through-hole capacitors are marked on the front side of
the box in plain text with brand name, capacitor series,
capacitance, nominal voltage, date code and tolerance.
Capacitors with PCM smaller than 15 mm will have the
tolerance indicated on the reverse. Standard tolerance
20% is not marked. |
PCM 2.5mm and
PCM 5mm film/foil |

| PCM 5mm metallized * |

 |
| PCM 7.5 and
10mm |
|
 |
| PCM 15
through 37.5mm |

The series
name MKS 2, FKP 3 etc. is composed as follows:
 The first letter indicates the
type of construction
The
second letter "K" stands for
plastic film capacitors.
The third
letter indicates the dielectric film used
| "S" |
= Polyester / PET
(other manufacturers are using "T") |
| "M" |
= Mixed
Dielectric |
| "P" |
= Polypropylene /
PP |
The
numbers following are WIMA-specific markings.
Metallized paper
capacitors are marked with "MP".
The cases of
2.5 mm and 5 mm capacitors are too small to imprint with
the series type (i.e. MKS 2, FKS 2 etc.). Instead, these
capacitors must be identified by different colours of the
marking inks and epoxy fill.

* As of September 2005 WIMA
changes step by step the metallized capacitors in
PCM 5 mm to top marking. Following series are
concerned:
