Copper-wound toroidal line filter for AC input EMI. Available as choke-only or with X/Y capacitors as a complete filter block.
Inductance: 100 µH – 10 mH class
View specificationBuilt to your measured emissions profile. Send the scan that failed and the current rating, and we design the filter around the frequencies that actually need attenuating rather than a generic curve.
Rated Current: To Specification
View specification10A line filter for drives, welding supplies and larger industrial equipment, wound on a core sized so the winding does not saturate at rated line current.
Common Mode Inductance: 1.5mH - 10mH
View specificationSingle-phase AC line filter rated 1A, for adapters, smart meters and small instrumentation. Attenuates conducted noise in both directions, so it also stops the supply polluting the mains.
Common Mode Inductance: 10mH - 33mH
View specification3A single-phase line filter for LED lighting, control panels and bench equipment. The usual first fix when a supply fails conducted emissions in the low megahertz.
Common Mode Inductance: 5mH - 22mH
View specification6A line filter for industrial supplies and motor controllers. Available single or dual stage where a single stage leaves too little margin.
Common Mode Inductance: 3mH - 15mH
View specificationCommon-mode line filter choke around 1 mH at 0.95 A for compact EMI stages. Wound and tested in-house.
Inductance: 1 mH class
View specificationCompact toroidal line-filter inductor around 48 µH at 2 A for differential / hybrid filtering stages.
