OCL (Open Circuit Inductance) Test parameters: 100kHz, 0.1Vrms, 0.0Adc 2. Inecessary for AC currents. PCB layout, trace thickness and width, air-flow, andrms DC current for an approximate ΔT of 40°C without core loss. Derating is 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. Isat Amps Peak for approximately 10% rolloff @ 20°C 4. Isat 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 ## **Dimensions–mm** **==> picture [468 x 101] intentionally omitted <==** **----- Start of picture text -----**
