The Amphenol
technologies to provide the user with the most cost effective
performance across the frequency range. (For EMP perfor-
mance data, see pages 172-175).
The tubular design offers over 40 years of proven field
reliability. All filter contacts within the connector share a
common ground plane, which is connected to the connector
shell. The pin to pin isolation is 85 dB minimum at 100 MHz.
The planar design joins pins to a multi-layered ceramic forming
an array sub-assembly, with a peripheral ground which is
connected to the connector shell via a ground spring. Pin to
pin capacitance is less than 50 pf with a pin to pin isolation of
85 dB minimum at 100 MHz. Filter contacts for both designs
contain either a pi passive element network comprised of a
ferrite inductor and ceramic capacitor, or a single capacitor.
