This snap type ferrite core is built with VN09 ferrite material. It comes with an initial permeability of 850 and Curie temperature over 130°C, delivering stable impedance at high frequencies. The separable clip design enables direct mounting over existing cables. No wire cutting or crimp modification is required. It suppresses high-frequency electromagnetic noise on wiring to improve EMI performance. The product meets ROHS and REACH specifications, suitable for EMC test calibration, on-site noise troubleshooting and volume pre-assembly. Dimensions: inner diameter 8.0 mm, outer diameter 23.0 mm, overall base width 26 mm.

Core function: Suppress conducted and radiated high-frequency EMI noise carried by cables, improve the EMC performance of electronic devices and support compliance certification including EN55014 and GB9254. The openable clip structure allows installation on already finished wire harnesses, serving as a practical accessory for EMC rectification.

Application fields:

• Consumer electronics: computers, displays, power adapters, audio and video cables, USB cables
• Industrial automation: PLC equipment, sensors, servo control lines, industrial communication cables
• Smart home: lighting drivers, smart household devices, surveillance cameras
• Medical electronics: signal and power wires for small and medium medical apparatus
• Automotive electronics, charging pile auxiliary wires, communication device wiring

Q1. What is the difference between different ferrite material grades?

A1. Different material grades have different permeability, impedance and operating temperature features. They are designed for noise suppression at different frequency bands.

Q2. Can multiple ferrite cores be used together on one cable?

A2. Yes. Installing several ferrite cores on the same cable can strengthen noise attenuation. It is recommended to separate them at a certain distance.

Q3. Does the ferrite core have polarity when installing?

A3. No. This split ferrite core has no polarity. There is no forward or reverse direction requirement during installation.

Q4. What is the main factor that decides the effective frequency range of a ferrite core?

A4. The ferrite material formula is the key factor. Core size and cable winding ways will also influence its working frequency range.

Q5. Is there any aging risk for ferrite cores during long time use?

 A5. Qualified ferrite cores have stable performance under rated working conditions. Normal aging is extremely slow and will not affect regular EMI filtering function.
