Fe-based 1K107 4*2.5*2.5mm Nanocrystalline Bead for Spike Suppression

Key Features

• High Inductance (17–19 µH/1Ts) at 10kHz, ideal for EMI filters and power converters, move noise significantly
• Ultra-compact size: only 4.5 × 1.5 × 3.5 mm (OD × ID × H, finish dimensions,  coated), Save PCB space
• Exceptional initial permeability (μi ≥ 80,000) , suppression noise significantly
• High saturation flux density (1.25 T) for robust current handling
• Low core losses at high frequencies due to nanocrystalline structure
• Wide operating temperature: -40°C to 140°C
