When ordering, please specify Tolerance and packaging codes: e.g. DO3316P-105MLD |
|
| Packaging: |
D = 13" reel, machine-ready EIA-481 embossed plastic tape (1000 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. |
|
| Tolerance: | M = 20%, K = 10% (Table above shows stock tolerances in bold.) | |
| 2 | Inductance tested at 100 kHz, 0.1 Vrms | |
| 3 | Tolerances in bold are stocked for immediate shipment. | |
| 4 | DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator. | |
| 5 | SRF >13 MHz measured using Agilent/HP8753D network analyzer; <13 MHz using Agilent/HP 4192A | |
| 6 | Isat: DC current at which the inductance drops 10% (typ) from its value without current. | |
| 7 | Irms: Current that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves. | |
| 8 | Ambient temperature range: | −40°C to +85°C with Irms current. Derating curve |
| 9 | 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) Derating curve | |
| 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. | ||
| PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info. | ||
