China Manufacturer V18007H H-Shape Ferrite Core NiZn Ferrite Core for EMC Debugging IoT Devices and Communication Hardware
Ni-Zn H-Type Ferrite Core V18007H High Impedance EMC EMI Noise Suppression for PCBA Wiring Harness
Product Overview
The V18007H is an EMI suppression ferrite core manufactured by Shenzhen VIIP Electronics Co., Ltd, designed for EMC noise suppression. This high-performance component effectively suppresses high-frequency electromagnetic interference within electronic circuits and fully complies with RoHS & REACH environmental requirements.
Impedance performance is verified with 10-piece production sample test data, targeting noise attenuation across the 1-500 MHz frequency range. Its toroidal gap-free magnetic-path design provides stable broadband noise-reduction performance for cable harness and circuit-level EMC optimization.
Key Features
- Standardized defect‑area & defect‑quantity limits for low breakage rate during winding and assembly
- Reliable mechanical strength, resists chipping and damage in mass‑production handling processes
- Works perfectly together with EMI filter circuits for prototype EMC troubleshooting and performance optimization
- Retains stable filtering capability under varying working‑temperature environments
- Noise reduction for short signal harnesses, internal equipment wiring and USB peripheral cables
