Y-Al series microwave ferrite materials

Y-Al Ferrites: The Heart of High-Frequency Magnetic Devices

What Makes Y-Al Ferrites Unique?

Yttrium-Aluminum substituted hexagonal ferrites (chemical formula：Ba₂YAlFe₁₁O₂₂) achieve breakthrough performance in microwave bands:

1. Ultra-Low Loss Tangent: 0.0003 @ 30GHz (40% increase compared to traditional Ni Zn ferrite)

2. High Saturation Magnetization: 4,800Gauss (Support Ka band applications)

3. Temperature Stability: Δμ < ±2% (-55°C to +125°C)

Certified for MIL-STD-202G vibration & MIL-STD-810H thermal shock standards.
