8F51/8AF51
8F526/8AF526
Description
8F51 and 8F526 circular filter connectors are
widely used in industrial, military and
aeronautical applications. They are suitable
for severe operating conditions.
Applications
- Military
- Aeronautical
- Industrial
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.

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.
