| 1 | Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4263B LCR meter or equivalent. | |
| 2 | DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator. | |
| 3 | SRF measured using an Agilent/HP 4191A or equivalent. Details | |
| 4 | Isat: DC current at 25°C that causes the specified inductance drop from its value without current. Temperature derating curves. |
|
| 5 | Irms: Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves. | |
| 6 | Ambient temperature range: | −40°C to +85°C with (40°C rise) Irms Derating curves |
| 7 | Storage temperature range: | Component: −40°C to +125°C Packaging trays or tape: −40°C to +80°C |
| 8 | Maximum part temperature: +125°C (Ambient + temperature rise) | |
| 9 | 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. | |
| 10 | 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. | ||
