Powell Electronics stocks EESeal+ EMC filters from Quell
Among the connectors and components for defence, aerospace and industrial applications available from Powell Electronics, the supplier now stocks Quell’s EESeal+ EMI filter inserts with improved attenuation and 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. Customised samples are available at very short lead times.
Quell’s patented EESeal+ technology 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, said Powell. Peak attenuation is around 45 to 50dB and frequency mitigation up to 100GHz has been reported.
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.
Powell Electronics specialises in high reliability, harsh environment connector design, manufacturing and supply chain. In the USA, Powell has 70,000 square feet of connector manufacturing capabilities at its Swedesboro, NJ facility, which is certified to ISO9001 and AS9100. Powell offers automated engineering solutions and connector ODM services. The company is an authorised, QPL’ed distributor for over 50 military specifications and is ISO9120-certified.
Powell Electronics’ European operations are in Dublin, Ireland, employing technical staff to support design-in activities and offering franchises agreements with Glenair, Harwin, Amphenol Aerospace, Quell, AB Connectors, Lemo, Conesys and Positronic. Powell says it can address a broad range of connector applications with products that range from miniature PCB-mount devices to high voltage, high current hi-rel solutions.
