2. What is EMI?  EMI (Electromagnetic Interference) is broadly defined as any unwanted electrical or electromagnetic energy that causes undesirable responses, degraded performance, or failure in electronic equipment.  For our purposes we are usually concerned with radiated and conducted EMI in electronic equipment in command, control, information and communication systems.  A basic working definition

3. Sources of EMI and EMP  High frequency devices  Electronics/computers  Cell phones/radios  Wireless/RF energy  Microwave equipment  Power lines  Electric motors  Electrostatic discharge (ESD)  Lightning (LEMP)  Nuclear event (HEMP)  Others  Radiated and Conducted

4. Electromagnetic Compatibility (EMC)  In a perfect world, every electronic enclosure would have six (6) sides and be completely sealed or welded, with no holes or apertures, providing 100% electronic shielding and containment.  In the real world, electronic enclosures have doors or removable sides, switches, connectors, indicators and gauges, thru- bulkhead fittings, and other openings that need to be electrically “closed” via conductive shielding products and technologies  Glenair is in the EMC business!

5. EMC Technologies  Cable and wire shielding  Grounding springs and pins  Shielded boxes and cases  Conductive platings  Conductive gaskets  EMI backshells  Conduit solutions  Capacitor and diode filter devices  Delivering clean data streams, undistorted by EMI,  requires a multi-disciplinary approach

6. What is a Filter Connector?  Filter connectors use internal capacitors and (optionally) inductors and diodes (for EMP applications) to “strip off” unwanted noise or transient voltages from the signal.  Types include tubular, planar array, chip on flex/board, EE seal and others  “Low-pass” filters attenuate high-frequency noise and allow low- frequency signals to pass  Each application environment dictates different capacitance values and cut-off frequencies to affect desired performance  Virtually any standard connector type can be outfitted with filtering technology  A basic working definition

7. Why Use a Filter Connector?  Easiest permanent EMI/EMP solution – designed to strip off conducted EMI before it passes through the device.  Variable capacitance from 500 pf to 50,000 pf  Small package size – doesn’t consume PCB real estate.  Can easily replace existing non-filtered connector.  Mates with standard connectors – 5015, 26482, 38999, 24308, 83723, 26500, 83513, Mighty Mouse, ARINC, etc.  Moves filtering away from sensitive board electronics when a signal “barrier” is needed in a system.  Can shunt an unwanted electrical surge fast {1X10^-9}  Filters are can be a “planned” addition to an electronic package or, as frequently occurs, added after a problem has been discovered

10. Electrical Criteria in Filter Device Specification  Operating temperature Range  Working voltage  Current rating  Surge voltage  Dielectric withstanding voltage  Insulation resistance  Frequency Range of All Effected Equipment  Selection of filter device types is affected  by the electrical criteria of the equipment:

11. Multilayer Planar Capacitor Array  Most widely applied type of EMI filter  Design utilizes rugged ceramic capacitor arrays and ferrite inductors in a single block  Available with different capacitance values on individual pins  Connector shell protects the array from thermal, mechanical and environmental damage  Reduced size, weight and superior performance compared  to discrete discoidal or tubular capacitors

12. Architecture of the planar array enables mixed capacitance values as well as feed-thrus Basic Filter Array Module Elements

13. Planar Array Construction  The planar array is a monolithic block of ceramic containing a combination of capacitors, feed-thrus and ground lines/planes.

14. Common Filter Element Architectures The mechanical architecture of the capacitor and its inductive elements allows for optimization for different frequency ranges of interference  C Filter: Single element filter with low self inductance  Pi Filter: Dual capacitors with a single inductive element positioned between

15. Insertion Loss Evaluation  Measured in decibels (dB), insertion loss must be minimized in low-current electronic systems.  Entire interconnect system contributes to insertion loss; hence the need for grounding and shielding technologies.  Insertion loss values are predictable for each filter type.  Measure of the degradation experienced by a signal when a device, such as a filter connector is inserted into the transmission path (Pi)

16. EMP/HEMP  High Electro Magnetic Pulse (HEMP) refers to the detonation of a nuclear bomb at a high altitude, which generates a very fast pulse (RF) which can be captured by antennas and long unshielded lines, damaging sensitive electronic circuitry. Sometimes referred to as Nuclear EMP (NEMP).  Lightning can also generate destructive EMP. This is referred to as LEMP.  Other potential sources of EMP include electrostatic discharge (ESD)  “EMP can be produced on a large scale using a single nuclear device”  - Congressional Research Report

17. Glenair’s EMP Solution: Transient Voltage Suppression (TVS) Filter Connectors  TVS technologies shunt EMP voltage transients directly to ground  TVS diodes and diode modules are integrated into the filter connector package  Diodes can be removed/replaced with relative ease  Decision point: can the capacitor absorb the surge or is a TVS device needed to reduce the surge – or both.  Products meet RTCA DO-160 Requirements (electrical performance benchmarks for withstanding EMP, HEMP, lightning strike and other induced voltage surges)

18. Protecting Sensitive Circuits from EMP  Glenair manufactured EMI/EMP Sub-Assemblies

19. Special Technical Considerations and Connector Packaging Options  Space grade applications  Hybrid fiber optic/electrical  Soldering procedures vs. clips  Lead free designs for RoHS  Composite materials and lightning  Hermetic sealing  Operating temps to -55° to 125°C  Machined shells/flange location  Clinch nuts/helicoils  Fixed contacts vs. crimp contacts  Variable length PC tails  EMI grounding fingers and gaskets  Package size issues, such as occur with the addition of crimp contacts or TVS diodes.  Filtered connectors are usually “system” qualified.  Most filter connectors are “custom.”  Some design decisions affect performance and compliance

20.  Non-Filtered interconnect systems can be easily upgraded with the addition of a go- between filter adapter.  Filtered Glenair Sav-Con Adapters are installed between the existing plug and receptacle—enabling 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- DTL-24308, MIL-C-83513, and others Filter Adapters (Connector Savers)
