1. Open Circuit Inductance (OCL) Test parameters: 1MHz, 0.100Vrms, 0.0Adc @20°C.

2. Irms: DC current for an approximate ΔT of 40°C without core loss. Derating is necessary for AC

currents. PCB layout, trace thickness and width, airflow, 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.

3. Isat : Peak current for approximately 30% rolloff @ +20ºC.

4. Applied Volt-Time product (V-μs) across the inductor. This value represents the applied V-μs at

500kHz necessary to generate a core loss equal to 10% of the total losses for 40°C temperature rise.

5. Part Number Definition: FP4-xxx-R

FP4 = Product code and size

xxx= Inductance value in uH, R= decimal point

-R suffix = RoHS compliant
