Flat Wire Vertical-Wound Common Mode Choke with Racetrack Core Design

The combination of a racetrack core and vertical flat-wire winding delivers minimal copper loss and exceptional high-frequency EMI filtering within a minimal space. It is purpose-built for demanding applications including EVs, server power supplies, and industrial automation.

  • Product Description

Flat Wire Vertical-Wound Common Mode Choke with Racetrack Core Design

 

This flat-wire vertical-wound common mode choke features an innovative racetrack core design that significantly optimizes the magnetic path and window utilization. The combination of vertical winding technology and flat copper wire drastically reduces direct current resistance (DCR) and high-frequency skin effect, enabling high current-carrying capacity with minimal heat generation. Its compact, low-profile structure saves critical PCB space while delivering exceptional thermal management and mechanical stability. With ultra-low parasitic capacitance, it provides broad-frequency and highly efficient EMI common mode noise suppression, making it an ideal component for high-power-density power systems.

 

 

Key Features

  • Excellent Core Performance: The nanocrystalline material features high permeability and high saturation magnetic flux density. This means that fewer winding turns are needed to achieve greater inductance and impedance, with significantly superior high-frequency interference suppression compared to traditional ferrite cores.

  • Excellent Heat Dissipation and Temperature Rise Control: The flat-wire vertical winding structure creates more gaps between coils, increasing heat dissipation space, effectively reducing the temperature rise during operation and enhancing product reliability.
  • Low Distributed Capacitance and Good High-Frequency Characteristics: The flat-wire vertical winding method results in lower distributed capacitance between windings, which facilitates the filtering of higher-frequency interference signals and improves overall filtering effectiveness.
  • Suitable for Automated Production: The racetrack or rectangular core shape combined with flat wire is better suited for automated winding equipment, addressing the difficulties associated with winding on traditional circular cores, and helping to improve production efficiency and product consistency.
  • Excellent Temperature Stability: Nanocrystalline materials have a high Curie temperature and can operate stably over the long term in environments up to 180°C, making them particularly suitable for applications with stringent temperature requirements, such as electric vehicles and industrial power supplies.
