Question What is the core advantage of V18030 magnetic ring with VN09 material

Answer This magnetic ring owns initial permeability of 850 and stable performance within wide temperature range. It features low loss at 0.01MHz high saturation flux density and high Curie temperature. It can keep good noise suppression effect under continuous working condition. Consistent batch parameters make it fit automatic winding production and help end products pass EMC related tests.

Question What kind of winding suggestion for this V18030 ferrite core

Answer Actual winding turns shall be confirmed according to your working frequency current requirement and noise reduction target. Too few turns may lead to insufficient noise suppression while excessive turns will bring extra parasitic capacitance. You can provide your circuit parameters and working condition we can give practical winding reference suggestion for your evaluation.

Question What conditions will cause magnetic saturation of this toroidal core

Answer Excessive working current is the main cause of magnetic saturation. When actual current exceeds the bearing capacity of the magnetic ring its noise filtering performance will drop sharply. High operating temperature beyond the allowable range will also affect its magnetic properties. Please select and use the product within specified working parameters.

Question Can you provide samples of V18030 magnetic ring for performance test

Answer Yes sample service is available. You can apply for samples to verify actual filtering performance before bulk purchase. Our samples keep the same material and production standard as mass goods. After sample confirmation we can arrange stable mass delivery for your formal order.

Question What is the difference between VN09 material and other ferrite materials

Answer VN09 material balances permeability loss factor and saturation flux density. It shows good comprehensive performance for medium and low frequency EMI suppression. Compared with high permeability material it has higher saturation value and better high temperature resistance. Compared with low permeability material it provides stronger noise absorption capacity for signal and power circuits.
