MIL-C-24308 Filter Connectors
ITT Cannon has developed a line of filter connectors
to meet the industry's demand fo improved control
of Radio Frequency and Electro-Magnetic Inter-
ference (RFI/EMI). These TD1* filter connectors,
have been designed to combine the functions of a
standard electrical connector and feed-thru filters
into one compact package. In addition to offering
greater design flexibility and system reliability, they
are designed for applications where space and
weight are prime considerations. These connectors
are intermateable with all standard D subminiature
TD1*
connectors. They are also intermateable with MIL-
C-24308 types and meet applicable portions of that
specification.
ALL TD1* filter contact assemblies are tested 100%
during in-process and final inspection, for capac-
itance, insulation resistance and dielectric with-
standing voltage. Attenuation is checked as re-
quired for each type of filter to assure performance
to guaranteed levels.
Note: The TD1* replaces the obsolete TD*J and D*J Series
