Part Number Definition: FP1308-xxx-R
• FP1308 = Product code and size
• xxx= Inductance value in μH, R = decimal point. If no “R” is present, then
third character = # of zeros.
I
: DC current for an approximate temperature rise of 40°C without core loss. Derating is
rms
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.
• “-R” suffix = RoHS compliant

I
: Peak current for approximately 20% rolloff at +25°C.
