Nanocrystalline cores for cable assembly

31 July 2026 Passive Components

Würth Elektronik expands its cable interference suppression program. Conventional MnZn and NiZn ferrite cores for cable assembly are now complemented by nanocrystalline cable cores. The WE-NCC series provides broadband suppression of conducted electromagnetic interference and features a compact design, high temperature stability and exceptionally high permeability.

Compared with conventional MnZn and NiZn ferrite cores, the nanocrystalline cores have significantly higher low-frequency impedance and broadband impedance behavior. WE-NCC is available for cable diameters from 3,7 to 21,1 mm. The initial permeability ranges from 30 000 to 90 000. Magnetic flux density reaches up to 1,2 T, while the Curie temperature is above 540°C. These properties ensure stable magnetic behavior across a wide temperature range and effective filtering over a broad frequency spectrum. The cable cores are suitable for interference suppression in cables used in industrial electronics, inverter technology, wind turbines, frequency converters, motor drive systems, among other applications. The nanocrystalline material enables smaller core dimensions with the same or better insertion loss than conventional cores. It also offers a significant weight advantage over MnZn cores.
