CURRENT (A)

1.	Tolerance of inductance :	20%.
2.	Irated is the DC current	which cause the inductance drop less than 25% of its nominal inductance without current
	and the surface temperature of the part increase less than 45oC.
3.	Operating temperature: -20oCto 105oC (including self-temperature rise).
