This clip-on ferrite core adopts VN09 ferrite material. It features an initial permeability of 850 and a Curie temperature higher than 130°C, offering steady high-frequency impedance performance. Thanks to its split clamping design, it can be fitted onto cables directly, with no need to cut wires or redo terminations. It effectively mitigates high-frequency electromagnetic interference on cables for EMI optimization. All items comply with ROHS and REACH standards, perfectly fit for EMC test tuning, finished product interference troubleshooting and mass pre-installation. Dimensions: inner diameter 8.0 mm, outer diameter 23.0 mm, total base width 26 mm.

Core function: Reduce conducted and radiated high-frequency EMI noise transmitted via cables, enhance equipment EMC capability and help products pass compliance tests such as EN55014 and GB9254. The hinged split structure supports retrofitting on pre-assembled cable harnesses, which makes it a mainstream solution to resolve EMC issues.

Application fields:

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

Q1. Can this ferrite core eliminate all electromagnetic interference completely?

A1. It can greatly attenuate high-frequency EMI noise, but it cannot remove all interference 100%. It is suggested to combine it with other EMC measures for optimal results.

Q2. Will the ferrite core affect the normal transmission of my signal?

A2. It mainly targets high-frequency noise. It barely disturbs low-frequency power signals and regular working signals when selected with proper specifications.

Q3. What should I do if the cable diameter is much smaller than the core inner diameter?

 A3. You can loop the cable through the core several times to raise impedance and get better noise suppression results.

Q4. Can these ferrite cores be customized with different sizes or materials?

A4. Yes. We support custom ferrite cores of different dimensions and material grades to match your unique EMC requirements.

Q5. What is the suggested installation position for the snap-on ferrite core?

A5. It is best to mount it as close as possible to the noise source or the equipment port to achieve the ideal filtering effect.
