Astute Electronics is an authorised, franchised seller and technical partner for Quell Corporation’s ground-breaking EESEAL solution for EMI issues in harsh environment applications.

Increasing use of electronic devices has seen an increasing demand to reduce ‘cross talk’ in order to maintain integrity. Traditional filter connector solutions often incorporate the use of Planar technology or chip on board solutions to achieve desired results. Both solutions obtain desired results but in an environment of reduced ‘time to market’ the lead time can be prohibitive. EESEAL is delivered in considerably less than half the time of traditional solution.

Quell has brought the EESEAL range to the market this technology allows for the filtering to be achieved by using an EMI filter insert made of silicone rubber. The patented construction allows for EMI filtering and transient suppression to be contained within the insert which is produced of the same material as military grade connector interfacial seals.

Once installed, which takes around thirty seconds and requires no specialist tooling, the EESEAL adds an environmental seal to the connector. Size advantage is also apparent over traditional solutions as is weight saving – both critical in helping customers meet market demand for smaller, lighter weight components.

Quell is AS9100 certified and the EESEAL passes MIL 1344 testing, RTCA/D0-160 thermal cycling, MIL5400 and NASA outgassing requirements. Utilised by many global leaders in aerospace, space and defence industries EESEAL has solved over 14000 applications thus far. The ease of installation makes EESEAL ideal retrofit solution and can be easily fitted in the field as well as designed in at concept stage.

Astute Electronics is proud to represent Quell Corporation and introduce to its customers the EESEAL solution.

Quell EESeal®

Robust and Reliable construction

EESeal® Filter Inserts are made from the same resilient silicone rubber material commonly used in military and industrial connectors.

Fitted in seconds without special tools, EESeal® Filter Inserts are practically invisible once installed.  No need for bulky filters or specialist filtered connectors.

Safe for Operational Use

EESeal® Filter Inserts are not just a test solution.  Once installed in your connectors, they can cope with the harshest of environments.

EESeal® Filter Inserts pass the demands of harsh-environmental testing:

  • MIL-STD-1344 shock, vibration, salt-spray, durability, fluid immersion, porosity
  • RTCA/DO-160 thermal cycling, humidity
  • MIL-STD-5400 temperature/altitude
  • NASA outgassing

Versatile and Configurable

EESeal® Filter Inserts are fitted with discrete capacitors ranging from .5pF to 1uF with voltage ratings from 25wvdc to over 1000wvdc.

EESeal® Filter Inserts are fully custom designed, allowing pin-by-pin assignment of capacitor values.

And you can add MOVs, resistors, and other components too, making EESeal® Filter Inserts even more versatile.

Put us to the test, and see how quickly EESeal® Filter Inserts can solve your EMC nightmares.
