1. When ordering, please specify packaging code:
POE60D-12LD
D = 13″ machine-ready reel. EIA-481 embossed plastic tape (400 parts per full reel).
Quantities less than full reel available: in tape (not machine ready) or with leader
and trailer ($25 charge).
B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft iseliminating the need for multiple packaging codes. When ordering, simply change
the last letter of your part number from B to D.
2. Inductance is for the primary, measured at 250 kHz, 0.5 Vrms.
3. Peak primary current drawn at minimum input voltage.
4. DCR for the primary and for the secondary are with the windings connected in parallel.
5. Leakage inductance is for the primary winding with the secondary winding shorted.
6. Turns ratios are with the primary and secondary windings connected in parallel.
7. Output of the secondary is with the windings connected in parallel. Bias winding output is 12 V, 20 mA.
8. Designed to remain in continuous mode operation at power levels of 3 Watts and above.
9. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
