Golden Eagle High Permeability Magnetic Rod Coil 8x50mm 10x80mm 12x150mm Ferrite Core Inductor for Wireless Charger Receiver Module NFC Device Signal Filter Wholesale
🧲 Small Component. Big Signal Difference.
In RF communication and power electronics, the inductor is the heartbeat of your circuit. A poorly designed ferrite rod coil introduces noise, heat, and signal drift. Our rod core inductors are precision‑wound and 100% tested to give you clean, stable performance from prototype to production.
🔬 What Makes Our Coils Different
-
Core choice: NiZn (high frequency, 1–100MHz) or MnZn (power, <1MHz)
-
Winding technology: Computer-controlled layering – consistent spacing, no insulation damage
-
Terminal options: Tin-coated copper wire, SMD pins, or insulated leads
-
Shielding: Bare core for maximum sensitivity or screened sleeve for EMI reduction
