When ordering, please specify termination and packaging codes: MSS4020-104MLD Termination:L =RoHS compliant matte tin over nickel over phos bronze. Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37). Packaging:D =13″ machine-ready reel. EIA-481 embossed plastic tape (2000 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 D instead. 2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft SMD‑A fixture in an Agilent/HP 4263B LCR meter or equivalent. 3. SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD‑D test fixture. 4. DC current at 25°C that causes the specified inductance drop from its value without current. Click for temperature derating information. 5. Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Click for temperature derating information. 6. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
