Visit Quell Corporation, Home of EESeal(tm), EMI & Transient Suppressors

The Metatech Commercial Products Division (CPD) ( now QUELL Corporation) developed a unique line of EESeal(tm) EMI filters and transient suppressors. The EESeal(tm) provides EMI protection and an environmental seal. It is designed to easily slip between any pair of mating connectors and can also be readily removed and reinserted. Once installed the EESeal(tm) shunts high-frequency electrical signals to the shell or to any preselected pin of the connector. Custom configurations, connector types, colors, sizes and electric specifications are available. Rapid prototyping is offered (within days) to support compliance testing.

Measured frequency attenuation characteristics of several EESeal(tm) filters are shown below for different capacitor values; the performance of a 5000 pF 9 Pin DSub filter is also shown for an IEC 61000-4-4 electrical fast transient waveform.
