1) Typical Inductance with no DC. Tolerance of +10%.

2) Current which will produce a 20% reduction in L

3) Current which will produce a 50% reduction in L

4) Maximum DC current. This value is for a 40

C temperature rise due to copper loss, with AC flux

density kept to 10 Gauss or less. (This typically represents a current ripple of less than 1%)

5) Energy storage capability of component in micro Joules. Value is for 20% reduction in permeability.
