Applications
Description
MIL-C 38999
circular filter connectors are
widely used in military and aeronautical
applications. They are suitable for severe
operating conditions.
These connectors are based directly on
standard specifications :
They are intermeatable and interchangeable
as to the mounting with standard connectors
of the same series.

minimum attenuation (dB)
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.
