DuraFlux™ （DF60）具有高达20000高斯的饱和磁通密度值。相对于其它几款有更高的耐温性、耐电流性（直流叠加性能非常优异）、耐高频性能很好，更低的价格、其能量贮存能力比高磁通（HI-FLUX）磁粉芯还要高是我司特殊开发的一款产品在一些特殊的用法上常常可以替代MPP、High Flux。是高瓦特数电源PFC电感理想的选择。适用于Power factor correction (PFC) inductors、Output filter inductors for SMPS、Voltage regulation module (VRM) inductors。
在PFC等产品上常常可以替代MPP、High Flux。

DuraFlux™

Distributed air gap toroid cores made from a complex composition of Silicon iron and pure iron powders are compacted into toroidal shapes. The unique combination of high saturation flux density and high dc bias capability makes DuraFlux cores an ideal choice for demanding high energy storage applications. DuraFlux materials have an initial permeability of 60µi with standard core sizes from 6.35 to 100.0mm. Cores are coated with an epoxy coating which provides a tough outer surface with a minimum breakdown voltage of 500Vac. DuraFlux cores are colour coded in green.
