1 Open Circuit Inductance (OCL) Test Parameters: 100kHz, 0.10Vrms, 0.0Adc
2 Full Load Inductance (FLL) Test Parameters: 100kHz, 0.1Vrms, Isat1
3 Irms: 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.
4 Isat1: Peak current for approximately 30% rolloff at +25°C.
5 Isat2: Peak current for approximately 30% rolloff at +125°C.
6 K-factor: Used to determine Bp-p for core loss (see graph). Bp-p = K * L * ÎI * 10-3, Bp-p : (Gauss),
K: (K-factor from table), L: (inductance in nH), ÎI (peak-to-peak ripple current in amps).
7 Part Number Definition: FP1109-xxx-R
⢠FP1109 = Product code and size
⢠xxx= Inductance value in μH, R = decimal point. If no âRâ is present, then
third character = # of zeros
⢠â-Râ suffix = RoHS compliant
