Open Circuit Inductance (OCL) Test Parameters: 1.0 MHz, 0.1 Vrms, 0.0 Adc, +25 C 4. DCR tested from pins (1-2) and pins (4-3) 2. I : DC current for an approximate temperature rise of 40 C without core loss. Derating is necessary for AC currents. 5. Part Number Definition: FPT705-xxx-R rms PCB layout, trace thickness and width, air-flow, and proximity of other heat generating components will affect the FPT705 = Product code and size temperature rise. It is recommended that the temperature of the part not exceed +125 C under worst case operating xxx= Inductance value in nH, conditions verified in the end application. -R suffix = RoHS compliant 3.
