EMI Capabilities
For Maximum Design Flexibility, Continued
Amphenol provides a wide range of filtering solutions. You
can select your options for your particular interference
threats - VHF, UHF, HF or other filter ranges, then couple
with a connector package of your choice. Or give Amphe­nol
your custom shell design requirements for assistance in
designing your unique filter solution.

Planar Array
Assembly
EMI Filter connectors are intended for use in temperatures
from –55°C to +125°C. Attenuation will change with feed-
through 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 inter-
ested in determining the expected filter perfor­mance in an
impedance system other than 50 ohms may refer to page
284 of this catalog or may contact Amphenol Aerospace for
further assistance.
Capacitor and
MOV Planars
Tubular Filters and
Diode Contacts
It is suggested that the user analyze his system
require­ments for EMI protection in the following areas:
• Working voltage (DC or AC and Frequency)
• Peak voltage
• Desired attenuation at a given frequency level
• Any special capacitance limitations
Definition of Filter Contacts:
MF-1
HF-1
VHF-1
UHF-1
Medium Frequency
50 dB performance between 300 - 2999 KHz
High Frequency
50 dB performance between 3 - 29 MHz
Very High Frequency
50 dB performance between 30 - 2999 MHz
Ultra High Frequency
50 dB performance between 300 - 2999 MHz
Filter contacts can be provided in most frequencies in
con­tact sizes 22 or larger. Consult Amphenol Aerospace
for availability.
Tubular connector designs will meet 3 amps RF current
from –55°C through +125°C. Planar connector designs
will meet 5 amps.
* More in-depth information on attenuation is available in:
L-1146, General Design Guideline for EMI Filters and/or
TVS (Transient Voltage Suppression) Connectors.

L-1145, How to Specify Filter Connectors.
Contact Options
• Coaxial, concentric twinax, triax and quadrax contacts can be
included in arrangements of filtered contacts for signal or power
circuits (Please refer to the High Speed Contacts Section for
High Frequency Contacts for Multi-Pin Connectors).
• Filter contacts with differing cut-off frequencies can be mixed in
any given insert arrangement. (ratio 100:1 typical)
• Ground, insulated or filter contacts can be combined within the
same connector to meet unique or changing frequency
protect­ion requirements.
• Thermocouple contacts
• Diodes for EMP
Methods of Wire Termination
• Solder cup - wire termination
• PCB termination (Pre-tinning is available)
• Solderless wrap
• Amphenol^® UTS (Universal Termination System) allows crimp
termination. It uses crimp insertable socket contacts on
cond­ uctor wires. Sockets mate with filter pins within the
connector body. (Socket type M39029/57). (For further contact
informat­ion, see section, MIL-DTL-38999 Series I & II).
• Weld terminal for thermocouple contacts
