for maximum design flexibility
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 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.

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.

EMI Filter connectors are intended for use in temperatures
from –55°C to +125°C. Attenuation will change with feedthrough current and temperature.*
To assure reliability, connectors may be subjected to an
attenuation performance test verifying proper assembly and
grounding of the filters. Attenuation data on filter per
formance is stated in reference to a 50 ohm impedance
system in order to allow filter performance to be more
easily translated into real world impedances. Those interested in determining the expected filter performance in an
impedance system other than 50 ohms may refer to page
131 of this catalog or may contact Amphenol Aerospace for
further assistance.

Adapters
Filter adapters eliminate replacement of either existing mated pair. The
adapter provides the circuit protection at the MF, VHF and UHF levels,
and is an effective and economical method of introducing EMI/EMP
protection to an installed system. Adapters are to be placed between
mating faces. (See pages 171).
Printed Circuit Board Mount
Receptacle shell modifications that allow mounting directly to a PC board
or flex header. Stand-off shells are available in different configurations.
These offer improved reliability by eliminating external spacers and
washers. (See pages 140, 141, 146, 147,160 and 163).
Hermetic
The hermetic filter connector, while only approximately 1/2 inch longer
than standard series connectors, provides all the benefits of a hermetic
connector, plus EMI protection for sensitive circuits. The filter assembly is
protected by a fused glass insert within a unique steel housing. This design
provides the capability to tolerate high level static pressure while
maintaining a low level leakage rate. Consult Amphenol Aerospace for
more information.
Cylindrical Filter Protection Connectors are offered
in a wide range of styles, with custom designs for
special applications.
Composite
Composite shell filter connectors meet the MIL-DTL-38999, Series III
dimensional length, and offer a light-weight, corrosion resistant, durable
connector with the same high performance features as its metal counter
part. The composite filter connector utilizes planar technology to
accommodate VHF-1 or better electrical performance characteristics.
(See pages 138-141).
ESD Protection
Filter connectors with ESD (Electrostatic Discharge) protection are
available. These MIL-DTL-38999 Series I and III connectors have an added
feature of a Faraday Cage to shunt electrostatic discharge events to the
conductive enclosure on which the connector is mounted.
(See page 203).
Filtered Plugs
Filtered Plugs are designed for
applications where EMI protection is
essential, but access to the receptacle
is denied. Designed with the same comHermetic filter connector
ponents as a standard filter receptacle,
the filtered plug offers the option of being
mounted on the cable harness. It is a cost effective method of achieving EMI protection when length restrictions prohibit
inclusion of an adapter to the system. Consult Amphenol
Aerospace for availability.
Diode Connectors
Diode Connectors offer versatility with transient protection for sensitive circuits, such as TTL lines. Diodes can stand alone or be combined with other filters. (Pages 174-175).

Impedance Matching Formula
The following formula and example are offered in order to
determine the expected filter performance in an impedance
system other than 50 ohms.
Atten (dB) = 20 log10
1+
Z SZ L
Z12(ZS + Z L)
Example:
(1) Noise is 40dB above specification level at 100 MHz
(2) Input and output impedance are 10 and 100 ohms
respectively
(3) Amphenol® VHF 7000 pf filter has a 65 dB minimum
attenuation at 100 MHz and +25°C
Formula (Taken from Figure 1):
1.4 x 10-2= transfer impedance
for 65 dB in a 50 ohm system
Atten (dB) = 20 log10
1+
10(100)
1.4 x 10–2 (10 + 100)
Attenuation = 56.3dB
In this case, the 7000 pf VHF filter will give 56.3 dB which is
16.3dB below the desired reduction in noise (40dB) as stated
in the above problem.
Series II JT Series I LJT
ZS = source impedance
With the attenuation expressed in 50 ohms and the transfer
ZL = load impedance
impedance curve shown in Figure 1 below, a designer can relate
Z12 = transfer impedance
the expressed attenuation to the input and output impedance of
his circuit.

Special Tests/Processes
Acceptance Testing
All filter connectors undergo extensive acceptance testing to
assure product quality. An outline of standard acceptance
testing performed is as follows:
Mechanical Inspection
• Dimensional inspection of shells, keys, keyways and
mounting surfaces by either in-process inspection of components or inspection of final assemblies.
• Visual inspection of contacts, inserts and seals, gaskets and
surface finish of shells and hardware.
Electrical Tests
• Insulation resistance of filter contacts is checked 100% at the
working voltage and to the test limit listed for each filter in
the filter selection data table.
• Dielectric withstanding voltage is tested on 100% of filter
contacts at the voltage listed in the filter selection data table.
• Capacitance is tested 100% at 1KHz.
In addition to the standard acceptance testing and processes,
the following additional production testing and processing can
be provided upon request:
• Attenuation testing (through 100 MHz)
• Leakage inspection
• Thermal cycling/shock
• Burn-in
• De-gassing

tools, fixtures or extended downtime. Simply unmate the
existing cable harness from the receptacle; attach the
coupling nut to the receptacle on the unit; then mate the
cable harness to the receptacle side of the adapter. Several
design alternatives are available that will help ensure that
the adapter remains permanently attached to either the
cable harness or the unit receptacle.

The Amphenol ® MOV Connector offers the versatility of a
standard connector, with transient protection for sensitive
circuits.Transients in electrical circuits caused by a sudden
release of stored energy can originate within or outside of the
circuit and may be repeatable or random.
Regardless of frequency or origin, transient caused failures
generated by load switching, lightning, electrostatic discharge
(ESD) and electromagnetic pulse (EMP) can destroy unprotected IC components.
Compatible with present filter connector assembly
procedures, MOVs can be combined with existing filters.
Internal housing of the MOV offers weight and space savings
over other protection methods available today, and eliminates
costly and bulky exterior suppression mechanisms in
appropriate situations. MOVs are presently available in
contact sizes 22, 20 and 16.
Transient protection can be provided in receptacle, plug or
adapter configuration. These connectors are intermateable
