1. 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.
