| 1 | When ordering, please specify tolerance, termination and packaging codes: e.g. 2508-27NJLC | |
| Tolerance: | G = 2%, J = 5% (Table above shows stock tolerances in bold.) | |
| Termination: |
L = RoHS compliant tin-silver (96.5/3.5) over copper. Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) over copper or S = non-RoHS tin-lead (63/37) over copper. |
|
| Packaging: | C =
7" machine-ready reel. EIA-481 embossed plastic tape, 1000 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, 3500 parts per full reel. |

| 2 | Inductance and Q measured at 250 MHz, 0.1 Vrms, 0 A using an Agilent/HP 4291A impedance analyzer with an Agilent/HP 16193A test fixture. | |
| 3 | Tolerances in bold are stocked for immediate shipment. | |
| 4 | SRF measured using an Agilent/HP 8753 network analyzer and a Coilcraft SMD-D test fixture. Details | |
| 5 | DCR measured using a micro-ohmmeter. | |
| 6 | Irms: Current that causes a 15°C temperature rise from 25°C ambient. Details | |
| 7 | Ambient temperature range: |
–40°C to +125°C with Irms current. +125°C to +140°C with derated current. Derating curve |
| 8 | Storage temperature range: | Component: –40°C to +140°C Packaging: –40°C to +80°C |
| 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. | |
| 11 | Temperature coefficient of inductance: +5 to +70 ppm/°C. | |
