| Packaging: | D = 13"
machine-ready reel EIA 481 embossed plastic tape (175 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, at 1 kHz, 0.5 Vrms, 0 Adc using an Agilent/HP 4263B impedance analyzer or equivalent. | |
| 3 | Ipk: Peak primary current (1.1 A) drawn at minimum input voltage. | |
| 4 | DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator. | |
| 5 | Leakage inductance
is for the primary and is measured between pins 1 and 2 with all other windings shorted. |
|
| 6 | Capacitance is measured from pins 1,2 to pins 6,10 at 250 kHz, 0.5 Vrms. | |
| 7 | Ambient temperature range: | −40°C to +85°C |
| 8 | Storage temperature range: | Component: −40°C to +125°C Tape and reel packaging: −40°C to +80°C |
| 9 | Isolation (hipot): 15000 Vrms, one minute from primary and bias to secondary and sync. | |
| 10 | Electrical specifications at 25°C. | |
