There are three version miniature, film and metallized see below
for description of each.
Miniature -
WIMA plastic film capacitors in RM 2.5 mm are available as WIMA MKS 02
in metallized, re-curable version or as WIMA FKP 02 in impulse-resistant film /
foil version. As a dielectric polyester or polypropylene film is
used.
The
WIMA series in the RM 2.5 mm are front-contacted and have a very low
self-inductance due to the short length of the capacitor and its fully
contacted electrodes. In addition, in principle, the pulse or current
carrying capacity increases, the smaller the grid dimension can be designed,
since - assuming the same film thickness - to achieve a certain capacitance
value a larger strip length is needed.
WIMA
capacitors in the RM 2.5 mm are ideally suited for RF decoupling up to the
high-frequency range and open up new application possibilities in applications
with a small footprint and high packing density.
Film -
In
the film / film structure, the electrode is not vapor-deposited, but wound as a
metal foil together with the dielectric film. The components manufactured
in this way have due to the lower series resistance excellent pulse and current
carrying capacity and a very high insulation resistance.
The
film / foil construction is mainly used for capacitors of smaller
capacity. An advantage of this design is the easy contactability of the
metal foil coverings and the good pulse resistance. In order to avoid
breakdowns due to weak spots in the dielectric, the selected insulating film
thickness is always above the theoretical values resulting from the specific
dielectric strength.
WIMA
film / foil capacitors are available in two dielectric variants in the grid
dimensions 5 mm to 15 mm. Polyester dielectric (PET) capacitors are
suitable for general applications such as coupling, decoupling and
blocking. Polypropylene capacitors (PP) are used in the high-frequency
range. These include resonant circuits, power supplies, line deflection
circuits, oscillator circuits and the audio section.
Metallized -
For
metallized capacitors, thin aluminum layers (about 0.03 μm) are vapor-deposited
as an electrode on a plastic film. In a breakdown evaporated by the
short-circuit current of the thin metal coating around the defect and it
creates an insulating "yard". The capacitor remains functional
(self-healing). Metallized capacitors are characterized by their very
favorable capacity / volume ratio.
By
using ultra-thin films and corresponding manufacturing experience, high
capacitance values can be produced in very small housings. Polypropylene
capacitors (PP) are used in the high-frequency range. These include
resonant circuits, power supplies, line deflection circuits, oscillator
circuits and the audio section.
