When ordering, please
specify packaging code: e.g. POE13F-12LD |
|
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. |

Inductance is for the primary, measured at
250 kHz, 0.3 Vrms, 0 Adc |
| 3 |
Ipk: Peak primary current drawn at minimum input voltage. |
| 4 |
DCR for the primary and for the secondary are with the windings connected in parallel. |
| 5 |
Leakage
inductance is for the primary winding with the secondary winding 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 12 V, 20 mA. |
| 8 |
Ambient temperature range: |
–40°C to +125°C |
| 9 |
Storage temperature range: |
Component: –40°C to +125°C
Packaging: –55°C to +80°C |
| 10 |
Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between. |
| 11 |
Electrical specifications at 25°C. |
| Refer to Soldering Coilcraft Components before soldering. |
