What is EMI?

EMI (ElectromagneticInterference) is broadly definedas any unwanted electrical or

electromagnetic energy thatcauses undesirable responses,degraded performance, or failurein electronic equipment.

For our purposes we are usuallyconcerned with radiated and

conducted EMI in electronicequipment in command, control,information and communicationsystems.

What is a ilter Connector?

Filter connectors use internal capacitors and (optionally) inductors and

diodes (for EM% applications) to 2strip off3 unwanted noise or transient

oltages from the signal.

5ypes include tubular, planar array, chip on fle+!board, EE seal andothers

2ow0pass3 filters attenuate high0frequency noise and allow low0

frequency signals to pass

Each application enironment dictates different capacitance alues and

cut0off frequencies to affect desired performance 6irtually any standard connector type can be outfitted with filtering

technology

Insertion &oss E$aluation

Measured in decibels (d;),

insertion loss must be minimi9ed

in low0current electronic systems.

Entire interconnect system

contributes to insertion loss

hence the need for grounding

and shielding technologies.

Insertion loss alues are

predictable for each filter type.

EMP'EMP

High Electro Magnetic %ulse (HEM%)refers to the detonation of a nuclear bombat a high altitude, which generates a ery

fast pulse ($F) which can be captured byantennas and long unshielded lines,damaging sensitie electronic circuitry.&ometimes referred to as uclear EM%(EM%).

EM%. 5his is referred to as EM%. *ther potential sources of EM% include

electrostatic discharge (E&')

EMP can be produced on a large scale using a single nuclear device - Congressional Research Report

Non-Filtered interconnect systems can beeasily upgraded with the addition of a go-

between filter adapter.

Filtered Glenair Sav-Con Adapters are

installed between the existing plug and

receptacleenabling filtering without having to

change exiting connectors or box layouts

Glenair Sav-Con Filter Adapters can be built

for any connector series including MIL-DTL-38999, MIL-DTL-26482, MIL-C-83723, MIL-
