注释

Calculated output power based on 150 kHz operating frequency. Power varies depending on application.
When ordering, please specify termination and packaging codes: e.g. GA3157-ALD
Inductance is tested between pins 4 and 3 at 500 kHz, 0.5 Vrms, 0 Adc.
DCR is for each half of the primary and secondary.
Leakage inductance is for the primary with both windings connected in series and with the secondary windings shorted.
Based on Bsat of the core at 25°C and number of turns on winding 4-3.
2500 Vrms primary to secondary isolation.

端子:

L = RoHS compliant tin-silver over tin over nickel over phos bronze.
T = RoHS tin-silver-copper (95.5/4/0.5). (Special order, added cost)
S = non-RoHS tin-lead (63/37). (Special order, added cost)

包装:

D = 13″ machine ready reel. EIA-481 embossed plastic tape (600 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 is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to D.
