1. OCL (Open Circuit Inductance) Test parameters: 100kHz, 0.1Vrms, 0.0Adc
2. I
rms
DC current for an approximate ΔT 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 155°C under
worst case operating conditions verified in the end application.
3. I
sat
Amps Peak for approximately 10% rolloff @ 20°C
4. I
sat
Amps Peak for approximately 15% rolloff @ 20°C
5. K-factor: Used to determine Bp-p for core loss (see graph). Bp-p =K*L*ΔI.
Bpp: (Gauss), K: (K factor from table), L: (Inductance in μH), ΔI (Peak to peak ripple
current in Amps).
6. Part number definition:
FP3 = product code and size
xxx = inductance value in μH
R = decimal point (if no “R” is present, then last character equals the number of zeros)
“-R” suffix = RoHS complaint
