Amphenol Aerospace 

Amphenol®

The Company

Amphenol Canada Corp. a subsidiary of Amphenol Corporation,

is an international leader in the manufacture of Filtered

Connectors and Specialty Interconnect Devices, and has been

pioneering EMI and EMP technologies for more than 40 years.

Located in Toronto, Canada, our ISO 9001 certified facility

employs approximately 400 people. Our activities are dedicated

to the design, development and manufacture of EMI/EMP filter

connector products which are used in Commercial, Industrial,

Communications, Military and Aerospace applications world-

wide. Our expertise in understanding and supporting our cus-

tomers’ filter interconnect needs has earned Amphenol Canada a

reputation of quality and excellence among the world’s leading

users of electronic components.

What is a Filtered Connector?

A filtered connector is the combination of filter elements in a capacitors are mounted inside the connector between each of

connector, forming one neat, compact interconnect device that the contacts and the connector ground shell.

can filter unwanted EMI. The most popular configuration is when

Benefits

Better EMI Control – With minimized lead inductances and

short, direct paths to ground of the filter, performance

will typically out perform the same filter components on

a P.C.B. by a factor of three to one.

PCB Space Savings – Incorporating filter elements into the

connector, enables simplification of the required filter

schematic for the necessary performance plus a savings

of 2-4 square inches.

Cost Savings – Filter elements, such as inductors and capaci-

tors, must no longer be purchased, stocked, assembled

or tested. Fewer components means greater reliability at

lower cost.

Easy EMI/RFI Upgrade – These compact filtered connectors

fit standard non-filtered connector footprints. For

improved EMC performance, simply replace the existing

connector with a filtered connector.

EMC Compliance & Immunity – EMI that is generated

from the electronic device, radiated or conducted, will

be re-directed to chassis ground through the connector

shell. This same device will also protect the system from

external EMI/RFI noise (such as radio transmitters, ESD,

or natural phenomena such as lightning) in the same way.

Choosing the Right Capacitance for Your Filter Connector

(1) Determine the highest frequency that the filter connector

needs to pass unaffected.

(2) Which frequencies are causing trouble, either with

emissions or with immunity to interference?

(3) Scan the Insertion Loss charts on page 2 to select a filter

which provides little or no insertion loss (filtering) at the

frequency determined from step 1, yet gives the greatest

possible insertion loss at the frequencies determined in step 2.

Nominal Insertion Loss values described in this catalog are

hence, the filter connector may perform differently.

based on the Mil-STD-220 test method - a 50 ohm balanced load The final decision will be determined from actual EMI/RFI

and source impedance. Different systems will differ from this and testing of the equipment in question.
