SENDUST
TOROIDAL
POWER INDUCTORS
FEATURES
NOTES: Temp Rise T1 & T2 are calculated.
1) Ln = Nominal Ind. @ 0.0Adc
* Sendust Powdered Iron Toroidal Construction.
* Optimized For Use as High Frequency DC Chokes.
* Temp Rise Data: Ripple Currents < 10% @ 100KHz
* Low Cost Self Lead Construction.
L1 = Nominal Ind. @ I1 Adc, T1 Temp Rise
L2 = Nominal Ind. @ I2 Adc, T2 Temp Rise
2) I1 Represents a 1-20% Drop in Ln
I2 Represents a 20-40% Drop in Ln
* Lower AC Losses Than Normal Powdered iron
