High-frequency power applications face a critical challenge: eddy current losses in magnetic cores. SHINHOM's RC Series amorphous cut-cores solve this through two innovations:
1.Ultra-thin amorphous ribbon (0.02mm thickness) – disrupts eddy current paths.
2.Precision gap engineering – optimizes hysteresis loss trade-offs.
▲ Proven Gap Impact (Fig.3 in PDF)
At 100 kHz and 0.5T induction:
0.5mm gap: 120 W/kg hysteresis loss
0.8mm gap: ↓ 92 W/kg (23% reduction)
*Tested at 25°C ±3°C with UL94V-0 compliant cores.*
Why Gap Length Matters?
Larger gaps reduce core permeability, lowering hysteresis loss but increasing fringing flux (potential eddy loss). RC Series balances this via:
✅ Laser-cut gaps (Tolerance: ±0.05mm)
✅ Distributed gap design (Multi-segment air gaps)
RC Series Specifications Advantage
Leverage full RC series amorphous core specifications (Page 2):
RC-1000 core: 23.0 cm² effective area (Ae) at 981 cm³ volume
50% smaller than ferrite equivalents (e.g., 1.56T vs. 0.4T saturation)
Engineer's Action Plan
For your application (PFC/X-ray/UPS):
Calculate gap length using:
g=μ0⋅N⋅IBmax−Br1+AgAcg=Bmax−1+AcAgBrμ0⋅N⋅I
