脉冲电容An important construction criterion in the
manufacture of reliable, self-healing capacitors for pulse
applications is the current-carrying capacity of the contacts, i.e.
the connection between the terminating wires and the
electrodes.
The construction principle of the series WIMA MKP
10 consists of a non-metallized dielectric film and an carrier film
metallized on both sides acting as electrode. Thanks to the
metallization on both sides, the electrical conductivity is
considerably improved and the contact surface between the electrodes
and the schoopage layer is doubled. This results in better contact
and allows for high current and pulse loading capability. The
properties of metallized capacitors such as excellent self-healing
and high volume capacitance remain unchanged.
The WIMA FKP 4
series presents self-healing film/foil Polypropylene capacitors made
from a single metallized plastic film and metal foil electrodes in
series connection. This construction features a high volume
capacitance and at the same time high pulse loading
capability.
The WIMA FKP 1 series was developed for extremly
high pulse loads. It has an internal series connection, the metal
foil electrodes being combined with a floating electrode metallized
on both sides. The metal foil electrodes are safely contacted on
both sides of the end surfaces . At the same time the capacitor is
fully self-healing due to the floating electrode metallized on both
sides. As regards pulse loading capability, WIMA FKP 1 represents
the high-end of capacitor
technology. |
