| 1 | When ordering, please specify termination and packaging code: e.g. MLC7540-222MEC | |
| Termination: |
E =RoHS compliant tin-silver over copper terminations. 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. 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. D = 13" machine-ready reel EIA-481 embossed plastic tape. |
|
| 2 | Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft SMD‑A fixture in an Agilent/HP 4284A LCR meter. | |
| 3 | DCR measured at 25°C on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator. | |
| 4 | SRF measured using an Agilent/HP4291A impedance analyzer and an Agilent/HP 16193 fixture. | |
| 5 | Isat: DC current at which the inductance drops the specified amount from its value without current. Details | |
| 6 | Irms: Current that causes the specified temperature rise from 25°C ambient. | |
| 7 | Ambient temperature range: | −40°C to +125°C with Irms current. |
| 8 | Maximum part temperature: | The part may be operated without damage as long its temperature (ambient + self-heating) does not exceed +125°C. |
| 9 | Storage temperature range: | Component: −40°C to +125°C Tape and reel packaging: −40°C to +80°C |
| 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. | ||
