Note
1）	AL = inductance for N = 1 (tolerance +45 % / -25 %)
2）	The core dimensions and finished core dimensions shows a nominal ones.
3）	Nominal values of core cross section.
4）	The epoxy coating is generally suitable for direct winding. However, we recommend additional isolation between core and winding for enhanced isolation requirements. The epoxy coating meets UL94-V0, UL file NO.E305963.
