Smaller wire will result in slightly lower dimensions. 3) Current which will produce a 20% reduction in L 4) Current which will produce a 50% reduction in L 5) Maximum DC current. This value is for a 40OC 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%) 6) Energy storage capability of component in micro Joules. Value is for 20% reduction in permeability.
