AC currents. PCB layout, trace thickness and width, air-flow and proximity of other heat generat-
ing 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.

: DC current for an approximate ΔT rise of 40°C without core loss. Derating is necessary for
K: (K-factor from table), L: (inductance in μH), ΔI (peak-to-peak ripple current in amps).
Part Number Definition: UP2CU-xxx-R
• UP2CU = Product code and size
• xxx= Inductance value in μH, R = decimal point. If no R is present, then third digit
equals the number of zeros.

I
: Peak current for approximately 7.5% rolloff at 25°C.
