Description
8F51 and 8F526 circular filter connectors are
widely
used
in
industrial,
military
and
aeronautical applications. They are suitable
for severe operating conditions.
They are intermeatable and interchangeable
as to the mounting with standard connectors
of the same series.
8AF51 and 8AF526 adaptors are the solution
to
easily
retrofit
existing
non
filtered
<equipments.

Attenuation per MIL-STD-220 at 25°C
(with no applied voltage or current,
in 50
system)
The capacitance, insulation resistance and dielectric withstanding voltage are tested 100% on all contacts.
Note : M filter is the most popular filter. If you require other filter types, indicate the maximum operating voltage, maximum capacitance and minimum attenuation
required at various frequencies.
B filter is substancialy more expensive than other filters.
