1. When ordering, please specify termination and packaging codes:
2. Inductance shown for each winding, measured at 100 kHz, 0.1 Vrms, 0
3. DCR is for each winding. When leads are connected in parallel, DCR is
4. SRF measured using an Agilent/HP 4191A or equivalent. When leads
5. DC current, at which the inductance drops the specified amount from its
6. Equal current when applied to each winding simultaneously that causes
7. Maximum current when applied to one winding that causes a 40°C
8. Electrical specifications at 25°C.
Refer to Doc 639 “Selecting Coupled Inductors for SEPIC Applications.”
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.

Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or
S = non-RoHS tin-lead (63/37).
D = 13 machine-ready reel. EIA-481 embossed plastic
tape (500 parts per full reel).
B = Less than full reel. In tape, but not machine ready.
To have a leader and trailer added ($25 charge), use
code letter D instead.

Temperature rise calculation based on specified Irms
Coupled Inductor Core and Winding Loss Calculator
This web-based utility allows you to enter frequency, peak-to-peak (ripple)
current, and Irms current to predict temperature rise and overall losses,
including core loss. Visit www.coilcraft.com/coupledloss.
