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 20% rolloff at +25°C.
5 Isat2: 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: FP0805Rx-Rxx-R
• FP0805 = Product code and size
