脚距为7.5-37.5mm的金属电容WIMA capacitors
for demanding requirements cover a wide range of capacitances and
voltages and are available with Polyester, Polypropylene or Mixed
Film dielectrics.
For metallized capacitors a thin metal
coating serving as electrode is applied to the plastic film. This
method makes it possible to produce capacitors with a very
favourable capacitance/volume ratio. The WIMA MKS 4, with 220 μF/50
VDC, offers the highest capacitance rating in the WIMA range. A
further specific characteristic of metallized capacitors is the
excellent self-healing ability. In the case of an electric breakdown
the applied metal layer evaporates. The affected area is isolated
and the capacitor continues to function properly.
WIMA
capacitors for stringent requirements are available with values
ranging from 1000 pF through 220 μF with voltage ratings from 50 VDC
through 2000 VDC. In accordance with customer requirements, larger
box sizes can be supplied as 4-lead versions. Types with terminating
plates can also be manufactured on request. The advantage of this
method of construction, besides the improved mechanical stability of
the component on the board, is the excellent electrical contact
reliability. |
