1. When ordering, please specify

termination and packaging codes:

DO5040H-104MLD

Termination: L = RoHS compliant tin-silver

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.

Core material Ferrite

Core and winding loss See www.coilcraft.com/coreloss

Terminations RoHS compliant tin-silver (96.5/3.5) over copper. Other

terminations available at additional cost.

Weight 5.8 – 7.6 g (2.8 –12 µH); 5.7 – 7.0 g (15 –1400 µH)

Ambient temperature –40°C to +85°C with

Irms current, +85°C to

+125°C with derated current

Storage temperature Component: –40°C to +125°C.

Tape and reel packaging: –40°C to +80°C

Resistance to soldering heat Max three 40 second reflows at

+260°C, parts cooled to room temperature between cycles

Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C /

85% relative humidity)

Failures in Time (FIT) / Mean Time Between Failures (MTBF)

38 per billion hours / 26,315,789 hours, calculated per Telcordia SR-332

Packaging 175 per 13

″ reel

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 Tested with pure water or alcohol only. For other solvents,
