SMD Device

1 Open Circuit Inductance (OCL) Test Parameters: 100kHz, 0.10Vrms, 0.0Adc

2 Full Load Inductance (FLL) Test Parameters: 100kHz, 0.1Vrms,Isat1.

3Irms: 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.

4Isat: 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

K: (K-factor from table), L: (inductance in nH),

ΔI (peak-to-peak ripple current in amps).

7 Part Number Definition: FP1308Rx-Rxx-R

• FP1308 = Product code and size

• Rx = DCR indicator

• Rxx = Inductance value in

μH, R = decimal point.

• “-R” suffix = RoHS compliant
