 
DO1813H Series High Current
Surface Mount Power Inductors
| New RoHS part numbers are shown.
Lead was removed from terminations.
Last three characters indicate tolerance, RoHS compliance, and packaging.
(View old data sheet.) |
- Small high current inductor - only 0.24" x
0.35" x
0.197" high
- Very high current ratings - up to 10 Arms;
14.0 A saturating current
- Exceptionally low DC resistance thanks to the use of heavier
gauge wire
- Flat top and self-leaded design for reliable
surface mounting
- Robust temperature deflection prevents damage during solder
reflow
- Custom versions available
- RoHS-compliant. 260°C compatible. Tin-silver over
copper terminations
- COTS Plus tin-silver-copper and tin-lead terminations available
- Samples of all values are available in

When ordering, please
specify termination and packaging codes: e.g. DO1813H-473MLD |
|
|
Termination: |
L =
RoHS compliant tin-silver (96.5/3.5) over copper.
Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) over copper or
S = non-RoHS tin-lead (63/37) over copper. |
| |
Packaging: |
D = 13" reel, machine-ready
EIA-481 embossed plastic tape (1000 parts per full reel).
B = Less than full reel
In tape, not machine ready. To have a leader and trailer
added ($25 charge), use code letter D instead. |
|
2 |
Inductance tested at 100 kHz, 0.25 Vrms using an Agilent/HP 4263B LCR meter or equivalent. |
|
3 |
DCR limits at 20°C. |
|
4 |
Isat: DC current at which the inductance
drops 30% (typ) from its value without current.
Details |
| 5 |
Irms: Current that causes a
40°C temperature rise from 25°C ambient.
Details |
| 6 |
Ambient temperature range: |
–40°C to +85°C with Irms current.
+85°C to +125°C with derated current Derating curve |
| 7 |
Storage temperature range: |
Component: –40°C to +125°C
Packaging: –55°C to +80°C |
| 8 |
Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between. |
| 9 |
Electrical specifications at 25°C. |

Qualification Standards for complete environmental and
test data. |
