POWER INDUCTORS ^{SENDUST MATERIAL ( Al & Si & Fe )}
Although higher in core loss than MPP material, Sendust has approxi-
mately 50% more energy storage capacity. Sendust has approximately 2/3
the flux density of High Flux material, but has a much lower core loss.
Sendust is an ideal tradeoff between storage capacity, core loss and cost.

1) Selected Parts available in Clip Mount Style. Example: L-14702K
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^OC 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%)
