| 1 | When ordering, please specify termination and packaging codes: e.g. DO3340P-105MLD | |
| Termination: | L = Gold over nickel over phos bronze. Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37). |
|
| Packaging: |
D = 13" reel, machine-ready EIA-481 embossed plastic tape (225 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. |
|
| 2 | Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4263B LCR meter or equivalent. | |
| 3 | DCR measured at 25°C on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator. | |
| 4 | Isat: DC current at 25°C that causes a 10% (typ) inductance drop from its value without current. Temperature derating curves. |
|
| 5 | Irms: Current that causes a 20°C 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 Irms current. |
| 7 | Storage temperature range: | Component: −40°C to +105°C Tape and reel packaging: −40°C to +80°C |
| 8 | Maximum part temperature: +105°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. | ||
