Having Doubts? Our FAQ

Do Frigate filters cover both EMI and RFI spectrums in a single footprint?

Yes. Our entire standard catalog features dual-action attenuation topologies engineered to suppress both low-frequency conducted emissions (EMI) and high-frequency radiated interference (RFI) simultaneously, eliminating the need to cascade multiple filtering components.

Can Frigate customize EMI / RFI filters for unique physical or electrical constraints?

Yes, we offer comprehensive engineering customization, including tailored termination styles, specific footprint configurations, multi-stage topologies for extreme noise environments, and ultra-low leakage designs for medical compliance.

How do I select the right filter current rating for my system?

You should choose a filter with a rated current equal to or greater than the maximum continuous operating current of your equipment. It is safe to use a higher-rated filter, but overloading a lower-rated one will cause overheating and potential failure.

We are failing EMC testing due to unexpected common-mode noise. How do your filters address this?

We optimize our multi-stage networks with high-permeability nanocrystalline or manganese-zinc ferrite cores that provide exceptional common-mode inductance. If standard off-the-shelf options aren’t arresting your specific noise spikes during compliance testing, our engineering team can rapidly adjust the internal Y-capacitor configuration to target the problem frequencies without exceeding your leakage current limits.

Are Frigate EMI / RFI filters compliant with global regulatory standards?

Absolutely. Our standard filter lineups are designed, manufactured, and tested to meet international standards including CE, UL, RoHS, and REACH, allowing your end-product to smoothly pass regional EMC audits.
