——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
