2.8 –12 µH parts Plastic tape: 44 mm wide, 0.5 mm thick,
24 mm pocket spacing, 12.8 mm pocket depth
15 –1400 µH parts Plastic tape: 32 mm wide, 0.4 mm thick,
24 mm pocket spacing, 12.1 mm pocket depth
PCB washing Only pure water or alcohol recommended
1. When ordering, please specify termination and packaging codes:
DO5040H-104MLD
Termination: L = RoHS compliant tin-silver 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
without 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.
