Filter-D
Series
PROFESSIONAL QUALITY, FILTER SUBMINIATURE-D CONNECTORS
FOR SHELTERED INDOOR/OUTDOOR ENVIRONMENTAL APPLICATIONS
Size 20 Contacts, Fixed
Professional Quality
Connectors
Capacitance Values
500pF through 30,000pF
IEC Publication 807-2
Where Applicable
Filter D-Series connectors are low profile, professional qual-
ity filter connectors recommended for use in sheltered, non-
corrosive indoor or outdoor environments having normal venti-
lation, but without temperature or humidity controls. These
fixed contact connectors meet the material and dimensional
requirements of MIL-PRF-24308 and IEC 807-2.
The low profile design of the Filter-D connector utilizes an
internal planar ceramic filter whose capacitance can be select-
ed from values between 500pF through 30,000pF. An external
ferrite inductor can be added if required.
Five standard connector variants are offered in arrange-
ments of 9, 15, 25, 37 and 50 contacts. Each connector vari-
ant is available with contact terminations for solder, and straight
and 90° printed board mount terminations. Filter-D Series con-
nectors are mateable and compatible with all D-Subminiature
connectors conforming to IEC 807-2 and MIL-PRF-24308 hav-
ing floating contacts.
A wide assortment of printed board mounting hardware is
available from stock.
Filter-D Series connectors conform to EIA RS 232 and RS
449, and CCITT X.24 interface connector requirements.
