This split ferrite core is manufactured from VN09 ferrite material. It delivers an initial permeability of 850 with Curie temperature exceeding 130°C and stable high-frequency impedance characteristics. Featuring a clip-on structure, it can be mounted on cables straight away without wire cutting or re-termination. It efficiently attenuates high-frequency electromagnetic interference on wiring for EMI improvement. All products conform to ROHS and REACH regulations, well suited for EMC testing adjustment, finished-product troubleshooting and bulk pre-assembly. Dimensions: inner diameter 8.0 mm, outer diameter 23.0 mm, overall base width 26 mm.

Core function: dampen conducted and radiated high-frequency EMI noise from cables, boost the EMC performance of devices and assist products in passing compliance tests including EN55014 and GB9254. The hinged split design enables retrofitting on already assembled cable harnesses, making it a popular solution for EMC problem fixing.

Application fields:

• Consumer electronics: computers, displays, power adapters, AV cables, USB data lines
• Industrial automation: PLC units, sensors, servo control wiring, industrial communication cables
• Smart home: LED drivers, intelligent household appliances, surveillance equipment
• Medical electronics: power and signal cables for medium and small medical devices
• Automotive electronics, auxiliary cables of charging piles, communication wiring systems

Q1. What is the working principle of a ferrite core?

A1. It converts high-frequency electromagnetic noise into heat energy and dissipates it, so as to suppress interference on cables. It has little impact on low-frequency useful signals.

Q2. Should I wind the cable multiple times through the ferrite core for better filtering?

 A2. More turns generally create higher impedance and better noise suppression within a proper range. Please check the cable space and operating current before winding.

Q3. Is there a temperature limit for using this ferrite core?

A3. Its Curie temperature is above 130°C. It works normally under common working temperatures. Avoid continuous operation close to or over the Curie point.

Q4. Can I use this ferrite core outdoors?

A4. The standard version is suitable for indoor use. For outdoor scenarios with moisture or UV exposure, extra protective housing is recommended.

Q5. What is the difference between a split ferrite core and a solid toroidal ferrite core?

A5. Split clip-on cores allow easy installation on finished cables. Solid toroidal cores require threading wires through in advance and usually provide slightly better noise reduction.
