1 Open Circuit Inductance (OCL) Test Parameters: 100kHz, 0.10Vrms, 0.0Adc
2 Full Load Inductance (FLL) Test Parameters: 100kHz, 0.1Vrms,Isat1
3Irms: DC current for an approximate temperature rise of 40°C without core loss. Derating is
necessary for AC currents. PCB pad layout, trace thickness and width, air-flow and proximity of other heat
generating components will affect the temperature rise. It is recommended the part temperature not exceed
125°C under worst case operating conditions verified in the end application.
4Isat1: Peak current for approximately 20% rolloff at +25°C. 5Isat2:
5 Peak current for approximately 20% rolloff at +125°C.
6 K-factor: Used to determine Bp-p for core loss (see graph). Bp-p = K * L * ΔI * 10-3,Bp-p : (Gauss),
K: (K-factor from table), L: (inductance in nH), ΔI (peak-to-peak ripple current in amps).
7 Part Number Definition: FP1107Rx-Rxx-R
