UP2UC

UNI-PAC™ drum core power inductors

Tolerances are ±0.254 mm unless otherwise specified.

Do not route traces or vias underneath the inductor

Packaging information-mm

1 Open Circuit Inductance (OCL) Test Parameters: 100 kHz, 0.25 Vrms, 0.0 Adc

2 Irms: DC current for an approximate ΔT 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 7.5% rolloff at +25 °C.

4 K-factor: Used to determine Bp-p for core loss (see graph). Bp-p = K * L * ΔI, Bp-p: (Gauss),

K: (K-factor from table), L: (inductance in

μH), ΔI (peak-to-peak ripple current in amps).

6 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.

• “-R” suffix = RoHS compliant
