1. When ordering, please specify
termination
and
packaging
codes:
GA3271-ALD
Termination: L
= RoHS tin-silver over tin over nickel over phos bronze.
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 250 kHz, 0.1 Vrms.
0.677 max
3. Peak primary current drawn at minimum input voltage.
17,20
4. DCR for the primary and for the secondary are 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 primary the secondary windings connected in parallel.
7. Output of the secondary is with the windings connected in parallel. Bias winding output is 15 V, 20 mA.
8. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
