1. When ordering, please specify

termination and packaging codes:

DO1813H-473MLD

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, 1000 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 tested at 0.25 Vrms, 100 kHz, 0 Adc.

3. DC current at which the inductance drops 30% (typ) from its value

without current.

4. Current that causes a 40°C temperature rise from 25°C ambient.

5. Electrical specifications at 25°C.

Refer to Doc 362 “Soldering Surface Mount Components” before soldering.

Designer’s Kit C331 contains 3 of each part

Core material Ferrite

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

Terminations RoHS compliant tin-silver over copper. Other

terminations available at additional cost.

Weight 278– 315 mg

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 1000 per 13

″ reel Plastic tape: 16 mm wide,

0.3 mm thick, 12 mm pocket spacing, 5.4 mm pocket depth

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

see Doc787_PCB_Washing.pdf.

• High-current power inductance; up to 14 A saturating current

• Rugged self-leaded construction for reliable soldering
