When
ordering, please specify packaging code: e.g. C1495-ALD |
|
Packaging: |
D = 13" reel, machine-ready
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. |

Inductance is for the primary, measured at
250 kHz, 0.2 Vrms, 0 Adc |
| 3 |
Ipk
is 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 windings 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. |
