The Amphenol^® EMI filter connector utilizes two manufacturing
technologies to provide the user with the most cost effective
performance across the frequency range. (For EMP perfor­
mance data, see pages 332-336).
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. This
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.
For planar designs, other filter networks are available, ie.
T Type, L-C Type, C-L Type and C Type. An encapsulant of
oven-cured epoxy in the rear provides:
• Mechanical and thermal insulation of the ceramic
elements – mechanical loading can be accomplished
without capacit­or damage. Pins can be bent 90° and
straightened with no damage to the filter.
• Hermeticity (4.6 x 10^-3 cc/sec) – prevents water from
enter­ing through the rear of the connector in high
humidity envir­onments. Amphenol recommends using
metal protection caps during cleaning operations.
