Packaging information - mm

1 Open Circuit Inductance (OCL) Test Parameters: 100 kHz, 1.0 Vrms, 0.0 Adc

2 Full Load Inductance (FLL) Test Parameters: 100 kHz, 1.0 Vrms, Isat1

3 Irms: DC current for an approximate temperature rise 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

+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

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

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

7 Part Number Definition: FP1505Rx-Rxx-R
