It features high initial permeability up to 80000 and maximum permeability reaching 300000 as well as high saturation magnetic flux density of 1250 millitesla. The product carries stable magnetic properties across a wide working temperature range from minus fifty degree to one hundred fifty degree with high Curie temperature of five hundred seventy degree. We implement strict visual inspection standards to control surface defects for every finished core to guarantee consistent quality for mass production. Its compact dimension with outer diameter 28.8 millimeter inner diameter 16.6 millimeter and height 12.6 millimeter supports convenient winding processing and assembly for different kinds of inductive components.

Application Scope

This nanocrystalline toroidal core is widely used in power electronics and electromagnetic compatibility related industries. It fits for household power supply equipment industrial control cabinet communication power module new energy charging equipment and medical power units. It also works well in signal filtering modules lightning protection devices and high precision testing instruments that need effective common mode noise suppression.

Usage

This nanocrystalline toroidal core is mainly wound with enameled wire to manufacture high performance common mode inductors for EMC filter circuits. It suppresses common mode electromagnetic interference on power lines and signal lines to help finished electronic products meet EMC test requirements. It can be matched with different winding turns and insulation structures according to customer actual circuit design to achieve expected filtering effect under different current and frequency conditions.

FAQ 

1. What is the main difference between nanocrystalline core and ferrite core Nanocrystalline core owns much higher permeability and saturation flux density than ordinary ferrite core. It shows better suppression effect for low frequency common mode interference and keeps stable performance under larger working current while ferrite core is more suitable for high frequency noise filtering scenarios.
2. Can I customize the size and material grade of magnetic cores We support customized development for magnetic core size shape and material grade based on customer circuit requirements. Customers need to provide detailed parameters such as working current working frequency and expected filtering targets for our technical evaluation.
3. What factors will affect the final filtering performance of the magnetic core The filtering performance is affected by core material grade winding method winding turns insulation treatment working current and working frequency. The installation position of the inductor inside the equipment will also bring obvious influence on the actual noise suppression result.
4. What is the storage requirement for these nanocrystalline magnetic cores The magnetic cores should be stored in dry and ventilated environment with stable room temperature. Avoid heavy extrusion collision and long time contact with corrosive liquid or gas to prevent surface damage that may influence winding work and magnetic stability.
5. Does your magnetic core support sample testing before bulk order We can provide samples for customer performance testing and EMC debugging. Customers can send their test feedback after sample evaluation and we will adjust the matching scheme to satisfy the formal production demand.
