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