Würth Elektronik has added nanocrystalline cable cores to its EMC portfolio, supporting broadband suppression of conducted electromagnetic interference in cable assemblies.
Würth Elektronik has expanded its cable interference suppression range with the WE-NCC series of nanocrystalline cable cores. The new series complements the company’s existing MnZn and NiZn ferrite cores for cable assembly and is designed to support broadband suppression of conducted electromagnetic interference.
The cores are intended for applications where cable routeduted interference can affect system performance, including inverter technology, frequency converters, motor drive systems and industrial electronics. These areas are relevant for electrified vehicle platforms, where EMC performance is an important factor in power electronics integration.
Compared with conventional MnZn and NiZn ferrite cores, the nanocrystalline WE-NCC cores provide higher low frequency impedance and broadband impedance behavior. According to Würth Elektronik, the material enables smaller core dimensions while maintaining comparable or improved insertion loss, and can also reduce weight compared with MnZn cores.
The WE-NCC series is available for cable diameters from 3.7 mm to 21.1 mm. Initial permeability ranges from 30,000 to 90,000, magnetic flux density reaches up to 1.2 T and the Curie temperature is above 540°C. These properties support stable magnetic behavior across a wide temperature range.
For vehicle and industrial applications with high electronic density, cable mounted EMC components can help reduce conducted interference and support more reliable operation of connected systems. In bus and coach platforms, this can be relevant for electric drivetrains, auxiliary power systems, control units and onboard electronic architectures.
With the WE-NCC series, Würth Elektronik is extending its EMC component offering for applications requiring compact, high permeability cable cores and broadband interference suppression.
