Magnetic Ring Inductors in Guitar Electronics

——Golden Eagle Ltd

(Compact · Low-Noise · High Stability)


1. Key Applications

Pickup Stabilization

  • Reduces 60Hz hum by 15dB (vs traditional coils)

  • Maintains signal clarity in single-coil designs

Effects Pedal Filtering

  • 10mH-500mH range for tone shaping

  • <2% THD at 20kHz (critical for high-gain circuits)

Amplifier Input Stage

  • EMI suppression for tube amp preamps

  • Handles 5W+ power without core saturation


2. Technical Advantages
