Power Feed-Through Capacitors
Overview
Applications
Power feed-through capacitors enable a consistantly high
frequency performance to be combined with high current
capability. The have compact mechanical enclosures
and terminations which suit the use in many industrial
applicatons such as Telecommunications, Medical
Particularly suitable for use in screened rooms, medical
equipment, power supplies, high frequency welding
equipment, and telecom systems.
equipment and DC power systems. These capacitors are
mechanically robust to withstand use in normal high current
applications and yet sufficiently compact to enable system
integration. Under AC use, consideration must be given
to the leakage current caused by the capacitance value
in order to comply with equipment safety specifications.
Under both AC and DC usage a safe discharge after use
must be considered because of the substantial energy
which can be stored. These capacitors are designed so
that multiple high frequency resonances are minimized and
hence the performance is maintained over the operating
frequency range. The dielectric design of the capacitor
elements enables high level of voltage withstand capability
and handling of high transients. These products are fully
encapsulated in a UL-94 V0 polyurethane resin system.
