SENDUST TOROIDAL POWER INDUCTORS
FEATURES
* 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. * Lower AC Losses Than Normal Powdered iron
NOTES: Temp Rise T1 & T2 are calculated.
1) Ln = Nominal Ind. @ 0.0Adc 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
