Material Properties
Core Advantages
1.High-Frequency Loss Characteristics
●Low hysteresis and dielectric losses (<0.5 dB insertion loss) make them ideal for microwave applications (1–100 GHz).
●High isolation (>20 dB) suppresses electromagnetic interference (EMI) in signal processing.
2.Environmental Robustness
●Corrosion and oxidation resistance ensure reliability in harsh industrial environments.
●Machinable into complex shapes (e.g., toroidal, rectangular) with high mechanical strength.
Application Domains
Power Electronics
●Transformers & Inductors: High permeability (μᵣ = 1000–5000) enables miniaturization while reducing copper/iron losses.
●Common-Mode Chokes: Mitigate noise in high-speed data transmission (USB 3.0, HDMI 2.1).
Telecommunications
●5G Base Stations:
●Filters: Support millimeter-wave bands (24–100 GHz) for multi-channel signal separation.
●Power Amplifiers: Enhance linearity and efficiency for 5G high-data-rate requirements.
●Microwave Devices: Circulators/isolators ensure unidirectional signal flow with <0.5 dB insertion loss.
Sensors & Control Systems
●Magnetic Field Control: Used in motor drives and position sensors with ±0.1% accuracy.
●Energy Storage: Optimize pulsed power systems when paired with supercapacitors.
