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 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.
3. Isat: Peak current for approximately 10% rolloff at 25°C.
4. K-factor:UsedtodetermineBp-pforcoreloss(seegraph).Bp-p=K*L*ΔI,Bp-p:(Gauss), K: (K-factor from table),
L: (inductance in μH),

(peak-to-peak ripple current in amps).
5. Part Number Definition: UP5-xxx-R
• UP5 = 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.
