1) Selected Parts available in Clip Mount Style. 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 40
O
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%)
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.
