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

due to copper loss, with AC flux density kept to 10 Gauss or less.

(This typically represents a current ripple of less than 1%)

Well Suited for Switch Mode Power

Supplies and Regulator Applications.
