FAQs

EMI filters utilize the inherent properties of capacitive and inductive materials, by removing higher frequency noise from the signal. These components absorb/reflect the higher frequency noise that is mixed in with the “true” signal, effectively cleaning up the resulting signal.

The ground tabs do not compromise the environmental seal inside the connector. The ground tabs are designed to cross over the O Rings and make contact to the shell of the connector. The tabs are flexible enough that they conform to the O ring and allow the silicon O ring to seal over the top of the flex circuit material used for the FlexFilter’s grounding tabs.

Alternatively, some customers chose to install the filters with the ground tabs underneath the O Ring, ensuring there is absolutely no interference with the O ring. The compression of the O ring during mating provides positive downward pressure on the grounding tabs which increases the grounding tabs contact force, insuring superior grounding.

Written installation instructions are included in every FlexFilter shipment and are also available upon request.

Our standard FlexFilter inserts are available with up to 500VDC working voltage ratings. In some applications, we can provide higher voltages depending on your circuit’s specific requirements. Please contact our Engineering team with the details of your specific application to determine the maximum voltage rating

EMI Solutions FlexFilters have successfully passed the DO-160 section 22, 1,500 V lightning requirements.

Our FlexFilter inserts are designed to stay firmly secured inside your connector – attempting to remove them from the connector will most likely cause damage to the base flex material destroying the insert.

As a result, we strongly recommend NOT attempting to reuse the FlexFilters, as the bending of the insertion point diminishes the sturdiness and integrity of the product.

Yes, based on your system requirements, we can build our FlexFilter inserts with different capacitor values on every pin. EMI Solutions’ Engineering team is always available to assist in developing customized solutions that maximize the performance of our filters.
