1. When ordering, please specify termination and packaging codes:
HA3586-BLD
Termination: L = RoHS tin-silver (96.5/3.5) over tin over nickel over phos bronze.
1
Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37).
Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic tape (200 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.

2. Inductance is for the primary, measured at 300 kHz, 0.5 Vrms.
3. Peak primary current drawn at minimum input voltage.
4. DCR for the secondary is with the windings connected in parallel.
5. Leakage inductance is for the primary windings with the secondary windings shorted.
6. Turns ratios are with the secondary windings connected in parallel.
7. Output of the secondary is with the windings connected in parallel.
Bias winding output is 5 V, 20 mA.
Parts manufactured prior
to December 2011 may
be marked differently.
8. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
