DO3316H Series High Current
Surface Mount Power Inductors
- Very high current ratings - up to 17 Arms; 28 Asat
- Low profile and small footprint - only 0.51" x 0.37" x 0.25" high
- 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-Q200 Grade 3 (−40°C to +85°C)
- RoHS-compliant. 260°C compatible. Tin-silver-copper over copper terminations.
- COTS Plus tin-silver-copper and tin-lead terminations available
- Custom versions available
- Samples of all values are available in Coilcraft Designer's Kit C326
- Need parts for space, military or other critical applications? See Coilcraft CPS 563PKA series.

| 1 | When ordering, please specify tolerance, termination and packaging codes: e.g. DO3316H-472MLD | |
| Tolerance: | M = 20%, K = 10% (Table above shows stock tolerances in bold.) | |
| 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 (750 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, 0.1 Vrms using an Agilent/HP 4263B LCR meter or equivalent. | |
| 3 | Tolerances in bold are stocked for immediate shipment. | |
| 4 | DCR measured at 25°C on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator. | |
| 5 | SRF measured using an Agilent/HP 8753D network analyzer. Details | |
| 6 | Isat: DC current at 25°C that causes a 10% (typ) inductance drop from its value without current. Temperature derating curves. |
|
| 7 | Irms: Current that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves. | |
| 8 | Ambient temperature range: | −40°C to +85°C with Irms current. |
| 9 | Storage temperature range: | Component: −40°C to +125°C Tape and reel packaging: −40°C to +80°C |
| 10 | Maximum part temperature: +125°C (Ambient + temperature rise) | |
| 11 | 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. | |
| 12 | Electrical specifications at 25°C. | |
| Refer to Soldering Coilcraft Components before soldering. | ||
