Core Material Component – Computer, Electronic and Optical Product Manufacturing

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
