1. When ordering, please specify termination and packaging codes:
DO5040H-104MLD
Termination: L = RoHS compliant tin-silver (96.5/3.5) over copper.
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 (175 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.
2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using Coilcraft
SMD‑A fixture in Agilent/HP 4284A impedance analyzer.
3. SRF measured using Agilent/HP 8753D network analyzer and Coilcraft
SMD­‑D test fixture.
4. DC current at which the inductance drops 10% (typ) from its value with-
out current.
5. Current that causes a 40°C temperature rise from 25°C ambient.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
