Available through Powell Electronics are EESeal+ EMC filters from Quell offering improved attenuation & simple grounding
19 December 2022
Powell Electronics, supplier of connectors & more for hi-rel applications including defence, aerospace & industrial, is stocking Quell’s EESeal+ EMI filter inserts with improved attenuation & frequency mitigation.
The inserts are easily and quickly inserted into standard connectors in seconds without the need for any special tooling or soldering, forming an effective EMI filter and maintaining the environmental seal. Customized samples are available at very short lead times.
The products benefit from Quell’s patented EESeal+ technology, which uses EMC filter components embedded into a silicone rubber insert that matches the size, shape and pin configuration of the connector to be filtered. Transient suppressors can also be included. Users can specify which filter elements are required for each pin, allowing for the creation of a completely custom filter insert with widely varying capacitor values, shorts and opens as desired.
The EESeal+ technology benefits from lower contact resistance and lower inductance than standard EESeals due to the improved ground plane. Peak attenuation is around 45-50dB and customers have seen frequency mitigation as high as 100GHz. In addition to EMI filters the EESeal+ filters make it easy to ground pins to the shell such as the coaxial shields in Combo D-Sub connectors as well as ARINC and coaxial circular connections.
