| 1 | When ordering, please specify packaging code: e.g. UA8164-BEC | |
| Packaging: | C = 7"
machine-ready reel 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 C instead. D = 13" machine-ready reel EIA-481 embossed plastic tape. Factory order only, not stocked (1000 parts per full reel). |
|
| 2 | Inductance is measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A LCR meter or equivalent. |
| 3 | DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator. |
| 4 | Capacitance measured at 100 kHz, 0.1 Vrms. |
| 5 | Leakage inductance is for L1 and is measured at 100 kHz, 0.1 Vrms with L2 shorted | ||
| 6 | Isat: DC current applied to L1 at which the inductance drops 10% from its value without current. | ||
| 7 | Ambient temperature range: | −40°C to +85°C with Irms current. | |
| 8 | Storage temperature range: | Component: −40°C to +125°C. Tape and reel packaging: −40°C to +80°C |
|
| 9 | Maximum part temperature: +125°C (Ambient + temperature rise) | ||
| 10 | Resistance to soldering heat: Three reflows at >217°C for 90seconds (+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. | |||
| PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info. | |||
