Key features

Near-Zero Magnetic Noise: Fe-Si-Al core eliminates mechanical vibration and audio distortion for pure sound quality.

High Saturation Flux Density: Uniform air gap structure minimizes inductance drop under large current for stable signal output.

Low Loss & Long Service Life: Reduces high-frequency loss and temperature rise in 24-hour operation to prevent aging.

Full Customization Options: Customizable inductance, wire gauge, number of turns, mounting style, and core materials.

Fast Sample Lead Time: Sample delivery available within 3-7 days for rapid prototyping and testing.

Multi-Strand Wire Support: Supports double wire or 3x0.5 wire to reduce DC resistance and enhance capacity.

100% Quality Inspection: Every unit undergoes 100% inspection for inductance, DC resistance, and insulation.

Product Q&A

Q:Is this series suitable for MIC microphone audio circuits?

Yes. Optimized for audio filtering. Ultra-low magnetic noise removes background noise and distortion, ideal for mics, smart speakers, and Bluetooth audio devices.

Q:What is the working frequency range?

Frequency: 10kHz~1MHz, ideal for audio frequency and small power supply filtering.

Q:Can you customize inductance, wire gauge and pin size?

Full customization: inductance, wire diameter, multi-strand, lead length, pitch, and mounting.

Q:What are the differences between Vertical, Horizontal and Sleeve type?

Vertical saves PCB space. Horizontal stable for high-current. Sleeve adds insulation for vehicles.

Q:How long is mass production lead time?

Stock: 3-7 days. Custom specs: 7-15 days.
