VIIP V18001A Clip-on NiZn Ferrite Core Magnetic Ring EMI RFI Noise Suppressor for Cable EMC Anti-interference

V18001A is a snap-on NiZn ferrite magnetic ring developed by VIIP, adopting VN09 ferrite material. Its plastic housing reaches UL94-V2 flame retardant grade. It delivers impedance of minimum 85Ω at 25MHz and minimum 175Ω at 100MHz, offering excellent suppression for high-frequency EMI and RFI noise. The clip structure enables quick installation on finished cables without rewiring. Strict appearance inspection and consistent component performance help electronic manufacturers pass EMC certification smoothly.

1. Household appliances: power cords of air purifiers, air conditioners, microwave ovens, refrigerators and other smart home devices.
2. Consumer electronics: data cables, signal wires and connecting lines for audio, lighting and small electronic equipment.
3. Industrial control: internal wiring of small control modules and low-power electronic equipment that requires EMC anti-interference.

1. Suppress high-frequency electromagnetic interference conducted along cables, reduce EMI/RFI noise between equipment.
2. Prevent electromagnetic noise from affecting circuit operation, avoid chip misoperation and abnormal restart of devices.
3. Assist products to meet EMC compliance standards and shorten the EMC test rectification cycle for manufacturers.

1. Q: What is the working principle of clip-on ferrite core? A: The ferrite core absorbs high-frequency electromagnetic noise on the cable and converts noise energy into heat, so as to suppress EMI and RFI interference. It has little effect on low-frequency power signals.
2. Q: Where should I install the ferrite magnetic ring on the cable? A: It is recommended to install it close to the equipment port. Winding the cable through the core for multiple turns can improve the noise suppression effect when space permits.
3. Q: What is the difference between NiZn and MnZn ferrite core? A: NiZn ferrite is suitable for high frequency (MHz range) EMI suppression, ideal for signal lines and power cords. MnZn ferrite works better for low-frequency interference.
4. Q: Can one ferrite core solve all EMC failure problems? A: No. The ferrite core is one EMC solution. The overall EMC performance also depends on PCB design, grounding and filter circuit matching.
5. Q: Does the ferrite core affect the normal power or signal transmission of the cable? A: Properly selected ferrite core will not interfere with low-frequency power and normal signal transmission. It only attenuates unwanted high-frequency noise.
