V18007H is a high‑frequency Ni Zn ferrite core built on VN02 material formulation. Key mechanical specifications cover outer diameter 3.5±0.3 mm, inner diameter 1.8±0.3 mm and height 5.0±0.4 mm. This component comes with low‑field permeability rated at 650. It presents minimum impedance reading of 20Ω at 25 MHz and 40Ω at 100 MHz for effective high‑frequency noise attenuation. Boasting superior electrical resistivity alongside Curie temperature exceeding 140℃, it sustains consistent magnetic characteristics under regular operating conditions. Every unit undergoes thorough outward appearance examination throughout manufacturing workflow. This ferrite component satisfies RoHS compliance requirements, and we welcome prototype sampling as well as large‑volume purchasing requests.

This ferrite core serves for EMI and RFI high frequency noise attenuation applied to thin gauge signal lines and inner wire harness assemblies. It blocks undesired high frequency disturbances, lessens signal deformation and reinforces reliability of signal transmission. It aids end equipment to fulfill EMC regulatory certification standards.

It is widely applied for consumer electronics, digital devices, household appliances and small‑size industrial control equipment internal wiring for noise elimination.

Q What key parameters should we confirm when selecting a suitable magnetic ring?
A Working frequency, impedance requirement, core dimension and material grade are essential. Matching these indicators with your circuit condition can get ideal anti‑interference effect.

Q What are the common causes of magnetic core saturation?
A Excessive current, improper material selection and mismatched core size may lead to saturation. Once saturated, the magnetic ring will lose most of its noise suppression capability.

Q What are the main differences between Ni Zn ferrite and Mn Zn ferrite magnetic rings?

A Ni Zn ferrite fits high‑frequency scenarios with high resistivity. Mn Zn ferrite performs better under low‑frequency conditions and features higher permeability values.

Q Will slight scratches on the surface of magnetic rings affect practical performance?
A Minor surface scratches only affect appearance. It will not change internal magnetic properties. Deep cracks or chipping will cause performance failure and should be rejected.

Q What points should be noticed during the winding process of magnetic rings?
A Avoid excessive mechanical impact on the core. Keep proper wire turns and tension. Sharp edges may damage enameled wire and bring hidden risks to finished components.
