Würth Elektronik has expanded its interference suppression portfolio with the WE-NCC series of nanocrystalline cable cores. The new products are designed for cable assembly applications and complement the company's existing MnZn and NiZn ferrite core ranges.
The WE-NCC series is intended for suppression of conducted electromagnetic interference in industrial electronics, inverter systems, wind turbines, frequency converters, motor drives, and other applications where broadband EMI filtering is required.
Nanocrystalline Alternative to Ferrite Cores
According to Würth Elektronik, the nanocrystalline material used in the WE-NCC series offers higher low-frequency impedance and broader impedance characteristics than conventional MnZn and NiZn ferrite cores.
The company states that the material allows smaller core dimensions while achieving the same or better insertion loss than conventional ferrite solutions. A weight reduction compared with MnZn cores is also cited.
Initial permeability is specified between 30,000 and 90,000, depending on the part selected.
Broadband EMI Suppression
The WE-NCC family is available for cable diameters ranging from 3.7 mm to 21.1 mm.
Würth Elektronik specifies magnetic flux density of up to 1.2 T and a Curie temperature above 540°C. According to the company, these characteristics help maintain stable magnetic performance across a wide temperature range while supporting broadband interference suppression.
The cable cores are intended for use on power and signal cables where conducted electromagnetic interference must be reduced across a broad frequency spectrum.
Expanding the EMC Portfolio
Electromagnetic compatibility products have long formed part of Würth Elektronik's passive component portfolio. The addition of the WE-NCC series extends the company's range of cable-mounted interference suppression products beyond traditional MnZn and NiZn ferrite materials.
The company also provides EMC design resources, including technical documentation, webinars, application support, and its REDEXPERT component selection tool. The WE-NCC nanocrystalline cable cores are available from stock with no minimum order quantity requirement.
