Würth Elektronik WE-NCC Nanocrystalline Cable Cores

Introduction

Würth Elektronik WE-NCC nanocrystalline cable cores are passive EMI-suppression components designed to reduce conducted electromagnetic interference on cables and wiring harnesses. Their nanocrystalline magnetic material provides high impedance across a broad frequency range, making them suitable for demanding power and signal filtering applications.

Part Description

The WE-NCC series consists of nanocrystalline cable cores available in toroidal and cylindrical formats. These cores are installed around conductors or cable bundles to attenuate common-mode noise and improve electromagnetic compatibility (EMC).

Compared with conventional ferrite cable cores, WE-NCC components can deliver up to 90% higher impedance from 100 kHz to 100 MHz. This performance is particularly useful where broadband conducted-noise suppression is needed without major changes to an existing circuit or cable layout.

Key characteristics include:

• Nanocrystalline magnetic core material
• Broadband conducted EMI suppression
• High permeability for effective common-mode noise attenuation
• Up to 90% higher impedance than conventional ferrite cores in the 100 kHz to 100 MHz range
• Stable magnetic performance across a wide temperature range
• Toroidal and cylindrical mechanical options
• UL 94V-0 rated housing
• Suitable for power lines, signal cables, industrial wiring, and renewable-energy equipment

Applications

Potential applications for WE-NCC cable cores include:

• AC and DC power cable noise filtering
• Common-mode choke enhancement on cable assemblies
• Motor-drive and inverter output cables
• Switching power supply input and output leads
• High-current battery connections
• EV charging and onboard power electronics
• Industrial communication cables
• Sensor and actuator wiring
• Data and control cable EMI reduction
• Solar inverter cabling
• Wind turbine power and control wiring
• Retrofit EMC improvements in existing systems
