Example: L-14402K 2) Typical Inductance with no DC. Tolerance of +10%. See Specific data sheets for test conditions. 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. Specifications are subject to change without notice Dimensions are nominal, based upon largest wire size used with each toroid size. Smaller wire will result in slightly lower dimensions.
