1. OCL (Open Circuit Inductance) Test parameters: 100kHz, 0.1Vrms, 0.0Adc

2. I

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

4. I

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
