| 1 | When ordering, please specify termination and packaging codes: e.g. 1812DPS-473MLC | |
| Termination: | L = RoHS compliant gold over nickel over moly-manganese Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37). |
|
| Packaging: | C = 7"
machine-ready reel EIA-481 embossed plastic tape (600 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" reel, machine-ready EIA-481 embossed plastic tape. Factory order only, not stocked (2200 parts per full reel). |
|
| 2 | Inductance is per winding. Tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4263B LCR meter or equivalent. | |
| 3 | Q measured at 1 MHz. | |
| 4 | Isat: DC current at which the inductance drops 10% (typ.) from its value without current. Details | |
| 5 | Irms: Current that causes a 40°C temperature rise from 25°C ambient. Details | |
| 6 | Ambient temperature range: |
–40°C to +85°C with Irms current. +85°C to +125°C with derated current Derating curve |
| 7 | Storage temperature range: | Component: –40°C to +140°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. | |
| 10 | Temperature coefficient of inductance: +200 to +700 ppm/°C. | |
| Refer to Soldering Coilcraft Components before soldering. | ||
