This is a snap-on ferrite core made of VN09 material. It has an initial permeability of 850 and Curie temperature above 130°C. It features reliable high-frequency impedance performance. You can clip it directly onto cables without cutting or rewiring wires. It effectively suppresses high-frequency electromagnetic interference on cables for EMI rectification. It complies with ROHS and REACH standards, ideal for EMC debugging, finished product rectification and mass pre-installation. Size specification: inner diameter 8.0 mm, outer diameter 23.0 mm, total base width 26 mm.

Function: Absorb and suppress conducted and radiated high-frequency EMI noise on cables, improve equipment EMC performance, and help products pass EMC tests such as EN55014 and GB9254. The snap-open structure allows installation on pre-assembled wiring harnesses, which is a widely used component for EMC troubleshooting.

Application fields:

• Consumer electronics: computers, monitors, power adapters, audio and video cables, USB data cables
• Industrial automation: PLC, sensors, servo control cables, industrial communication wires
• Smart home: light drivers, smart home appliances, security monitoring devices
• Medical electronics: signal and power cables for small and medium medical instruments
• Automotive electronics, charging pile auxiliary wires, communication equipment wiring
  

Q1. Do I need to cut the cable to install this snap-on ferrite core?

A1. No cutting is required. Thanks to the snap-open design, you can clip it on the outside of the cable directly. It supports post-installation rectification and can be disassembled and reused.

Q2. How to choose the inner diameter of the ferrite core?

A2. The outer diameter of your cable should be smaller than the inner diameter of the core. A tight fit brings the best noise reduction effect.

Q3. Does the ferrite core work on both power cables and signal cables?

A3. Yes. It can suppress high-frequency noise for both power lines and signal lines.

Q4. What affects the noise suppression performance of the ferrite core?

A4. Material grade, core size, cable layout and the number of wire turns through the core will influence the final filtering result.

Q5. Are these ferrite cores environmentally friendly?

A5. Yes. Our ferrite cores meet ROHS and REACH requirements.
