| 1 | When ordering, please specify packaging code: e.g. SPT20L-112MLD | |
| Packaging: |
D = 13" reel, machine-ready EIA-481 embossed plastic tape. Standard series parts per reel. High Current series parts per reel. |
|
|
B = Less than full reel On tape not machine-ready. To have a leader and trailer added ($25 charge), use code letter D instead. |
||
| 2 | Inductance tested at 100 kHz, 0.1 Vrms on an Agilent/HP 4192A impedance analyzer. | |
| 3 | SRF measured using Agilent/HP8753ES network analyzer. Details | |
| 4 | Isat: DC current at which the inductance drops the specified amount from its value without current. Details | |
| 5 | Irms: Current that causes the specified temperature rise from 25°C ambient. | |
| 5 | Ambient temperature range: | –40°C to +85°C |
| 6 | Maximum part temperature: | The part temperature should not exceed +85°C (ambient + self-heating). Prolonged operation above +85°C may result in a permanent increase in core loss and part failure due to thermal aging of the core material. |
| 7 | Storage temperature range: | Component: –40°C to +85°C T&R packaging: –40°C to +80°C |
| 8 | 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. | |
| 9 | Electrical specifications at 25°C. | |
| Refer to Soldering Coilcraft Components before soldering. | ||
