Core Material

Core material for receiver coil assemblies in electromagnetic systems, providing magnetic flux concentration and energy transfer efficiency.

Component Specifications

Definition
Core material is the central magnetic component in receiver coil assemblies, designed to concentrate magnetic flux lines, enhance inductive coupling efficiency, and minimize energy losses during wireless power transfer or signal reception. It determines the coil's inductance, quality factor (Q), and frequency response characteristics.
Working Principle
Operates on electromagnetic induction principles where alternating current in a transmitter coil generates a magnetic field; the core material in the receiver coil concentrates this field to induce voltage, enabling efficient energy or signal transfer through optimized magnetic permeability and low hysteresis losses.
Materials
Typically ferrite (Mn-Zn or Ni-Zn), powdered iron, amorphous metals, or nanocrystalline alloys; selected based on frequency range (kHz to MHz), permeability (μr 50-5000), saturation flux density (0.3-1.5 T), and core loss specifications.
Technical Parameters
  • Core Loss <100 mW/cm³ @ 100 kHz
  • Permeability 100-5000 μr
  • Frequency Range 20 kHz - 10 MHz
  • Curie Temperature >200°C
  • Saturation Flux Density 0.3-1.5 T
Standards
ISO 9001, IEC 62368-1, ASTM A773
