When ordering, please
specify packaging code: e.g. POE13P-12LD |
|
Packaging: |
D = 13"
machine-ready reel
EIA 481 embossed plastic tape
POE30P (350 parts per full reel); POE70P (200 parts per full reel);
POE13P (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. |

Inductance is for the primary, measured at 250 kHz, 0.1 Vrms, 0 Adc |
| 3 |
Ipk is the peak primary current drawn at minimum input voltage. |
| 4 |
DCR for the secondary is per winding |
| 5 |
Leakage
inductance is measured between pins 3 and 4 with all other pins shorted. |
| 6 |
Turns
ratio is with 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 +85°C |
| 9 |
Storage temperature range: |
Component: –40°C to +85°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. |
