How EESeal® EMI Filter Inserts Work
Installs in seconds using only a fingertip — no tools or extra hardware required
Virtually invisible in use, adding less than one gram to overall connector weight
Built for the rigors of space, sea, or desert — resists shock, fluid immersion, and vibration
Silicone body mirrors pin layout, naturally compensating for mismatches and alignment

Get the Performance of a Filtered Connector, Without the Cost and Bulk
EMI filter inserts can save you 25–50% over a filtered connector solution with fast delivery. Fix common EMI & ESD compliance problems early in the design process with a lightweight, cost-effective alternative to bulky filtered connectors, or add on an EESeal at the testing facility to save yourself from a redesign.
