| |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 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
- AEC-200 Grade 3 (-40°C to +85°C)
- 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 Coilcraft Designer's Kit C331

| 1 | 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 T&R packaging: –40°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. | |
| Refer to Soldering Coilcraft Components before soldering. | ||
