| 1 | When ordering, please specify termination and packaging codes: e.g. GA3429-BLD | |
| Termination: | L = RoHS compliant tin-silver over tin over nickel over phos bronze Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37). |
|
| Packaging: |
D = 13" reel, machine-ready EIA-481 embossed plastic tape (250 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, 0.3 Vrms, 0 Adc using an Agilent/HP 4263B impedance analyzer or equivalent. | |
| 3 | Ipk: Peak primary current drawn at minimum input voltage. | |
| 4 | DCR for the secondary is per winding. | |
| 5 | Leakage inductance is for the primary winding with the secondary windings shorted. | |
| 6 | Output is with the secondary windings connected in parallel. Bias winding output: 3.3 V, 20 mA. |
|
| 7 | Ambient temperature range: | –40°C to +85°C |
| 8 | Storage temperature range: | Component: –40°C to +85°C T&R packaging: –40°C to +80°C |
| 9 | Electrical specifications at 25°C. | |
