Electromagnetic interference or pulse (EMI/EMP) is an unwanted signal that is either radiated or conducted to susceptible equipment and interferes with the performance of that equipment. The effect of EM/EMPI can vary from static to a complete malfunction of a navigation system.Electromagnetic Compatibility (EMC) requirements have been established to ensure that the performance of an individual electronic device is not degraded due to its proximity to high-frequency electromagnetic interference, and also to prevent the device itself from becoming a potential source of EMI. Sensitive electronic devices also need to be protected from voltage spikes generated during transient states or static discharges in the overall system.
Filtered connectors “strip off” unwanted noise or transient voltages from the signal. Filtered connectors are typically custom products with limitless variations in capacitance per line and virtually any connector type can be outfitted with filtering technology. If you have an existing EMI/RFI issue, Quell can design a solution for your application in one day!
Designing interconnect systems that deliver clean data streams, undistorted by EMI/EMP is a challenge. However; BTC is a franchised distributor for leading filter connector manufacturers like Glenair. Our team of experts provides world-class technical support and a wealth of experience and knowledge that will allow us to design and build a custom connector for your application.
Each connector series is offered with standard low-pass Pi or C filter arrays, or with customized filters to meet specific frequency and capacitance requirements. Thermally conductive epoxy protects the filter package from mechanical and heat stress and also provides a waterproof seal. All filtered receptacles are intermateable with standard plugs and connector savers, and each respective family of connectors is supplied with a range of shell styles in both environmental and hermetic configurations. BTC can provide custom EMI or RFI specialty and filtered connectors used in military and high-reliability applications in almost any style including these:
- Tubular and planar filtered arrays in Pi, LC, T, and C circuits with TVS protection
Benefits of Filtered Connectors
- Component Reduction
- Filtered connectors create cost savings by lowering component count
- Consistent Performance
- Filtered connectors provide consistent pin-to-pin performance
- Low Ground Impedance
- Full ground plate and metallic shell provide minimal impedance and superior performance compared to onboard filter with high impedance
- Eliminate Re-Radiation
- Filtered connector at interface offers no path for bypassing the filter
- Ground Plane Shielding
- Filtered connector ground planes shield the box even at the connector port
- Smaller Footprint on PCB
- Filters located in connector provides additional space on PCB board
- Our franchised/authorized manufacturers test 100% of filters, on-board filters are usually spot tested
