Typical filter attenuation
The ACARA connector has a current-carrying
conductor passing through the center of the
capacitor. This co-axial conductor is one ter-
minal of the capacitor. The other terminal is
the metal outer casing of the capacitor, which
was specifically designed for being attached
to a grounded metal bulkhead. This design is
common to all ACARA filters and ensures that
any radio frequency currents carried on the
central conductor are shunted to earth by the
capacitor.
Because of the extremely low series induc-
tance resulting from this type of construction,
the self-resonant frequency of an ACARA
capacitor will be very high. A typical frequency
response is shown below. As frequency
increases, the impedance of the feedthrough
capacitor decreases continuously to provide
excellent performance to beyond 10GHz.
Some small resonances can be expected in
the performance characteristics of ACARA
capacitors as shown below. These are usually
attributable to distributed inductance within
The combination of connector and filter
results in an effective solution to simplify the
contacting concept.
The ACARA filtered connector shows excellent
performance filtering high frequency noise on
the line, protecting computer systems, base
stations and other electronic systems.

response to vary slightly from the theoretical.

The success of ACARA depends on a very low
contact resistance, and this design provides
a very high quality material and a clever
metallization process so there is no risk of
over-heating effects. The hot-pluggable con-
nector has very low arcing between the male
and female connector. ACARA is designed for
500 connect/disconnect cycles and 250 cycles
under nominal load according UL1977 and
EN60984 giving optimum performance and
flexibility. Servers, base stations and telecom
equipment can easily be connected and
disconnected.
The material used in the contact and the
mechanical construction of ACARA are im-
portant to reach the service conditions of the
customer application. The diagrams above
show a typical temperature rise of a 100A
connector. The contact resistance of the
connector is most important. For example
with 100A nominal load, the temperature rise
of the contact is only approximately 17°C.
achieve this high conductivity copper is used
which gives a low temperature rise. The
copper material has good spring properties at
contact interface and with good formability
for crimping to finely stranded copper
conductors. The spring system provides high
mechanical shock/vibration stability with no
contact bounce.
The patented ACARA connector family offers
fast easy connecting and a long lifetime with
hundreds of connect/disconnect cycles. To

Important
The influence of a good earth contact is very
important. The overall performance of the
ACARA filter is reduced if there is a small
resistance between the connector ground
and chassis ground. The filter connector is
connected with the chassis via a special elec-
tric conductive gasket pre-assembled to the
connector. The gasket ensures low resistance
contact between the filter and the conductive
cut-out panel. The region where the gasket
is connected to the chassis ground should
not be painted or otherwise isolated. The
resistance has to be as low as possible.
In the diagram you will find the influence
between the resistance to ground and insertion
loss. This part of the installation is extremely
important for the filter performance.
