HELICAL EDGE WOUND TOROID INDUCTOR HT1500 SERIES • • • • • • • • Helical Edge Wound (HEW™) Flat Wire Toroid Inductors Low core loss Excellent heat dissipation Good DC bias characteristics Lower ACR than traditional round wire Extremely low interwinding capacitance Operating Temperature -40ºC to +150ºC Vertical and horizontal mount versions available (add -V or -H after part number for mounting version) ELECTRICAL PARAMETERS @ 25°C Part Number INDUCTANCE (μH) ±12% DCR (mΩ) MAX Isat (A) Typ 10% drop Isat (A) Typ 20% drop Isat (A) Typ 30% drop Irms (A) Typ 40ºC rise HT1500-121 120.0 65.0 5.8 8.5 11.3 6 HT1500-281 285.0 65.0 2.5 3.8 5.0 6 HT1500-361 360.0 65.0 2.0 3.0 4.1 6 Note: 1. Inductance measured at 10KHz, 1Vrms 2. Isat is DC current at which the inductance drops the specified amount from its original value without bias. 3. Irms is the DC current that causes the specified temperature rise of the winding from 25°C ambient for the inductor.
