Product Q&A

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

Yes. Specially optimized for audio filtering, ultra-low magnetic noise eliminates background noise and sound 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 switching power supply filtering.

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

Full customization supported, including inductance, wire diameter, multi-strand wire, lead length, pitch, and mounting type.

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

Vertical saves PCB space for mini modules. Horizontal is stable for high-current boards. Vertical with sleeve offers extra insulation for vehicle and outdoor devices.

Q:How long is mass production lead time?

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