 
DO3308P Series
Surface Mount Power Inductors
|
New RoHS part numbers are shown. The products were always compliant;
only the part numbers changed. Added characters indicate tolerance, RoHS compliance, and packaging. (Old data sheet can be viewed
here.)
|
- Very low profile - less than 0.118" (3 mm) high!
- High energy storage and very low resistance
- Flat top for reliable surface mounting
- Robust temperature deflection prevents damage during solder
reflow
- Defense Supply Center CID A-A-59738
- Custom versions available
- RoHS-compliant. 260°C compatible. Gold over
nickel
over phos bronze 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. DO3308P-105MLD |
|
|
Termination: |
L = Gold over nickel over phos-bronze
Special order, added cost: T
= RoHS tin-silver-copper (95.5/4/0.5) or
S = non-RoHS tin-lead (63/37). |
| |
Packaging: |
D = 13" reel, machine-ready
EIA-481 embossed plastic tape (1000
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. |

Inductance tested at 100 kHz, 0.1 Vrms. |
|
3 |
Isat:
DC current at which the inductance drops 10% (typ) from its value
without current.
Details |
| 4 |
Irms: Current that causes a
40°C temperature rise from 25°C ambient.
Details |
| 5 |
Ambient temperature range: |
–40°C to +85°C with Irms current.
+85°C to +125°C with derated current Derating curve |
| 6 |
Storage temperature range: |
Component: –40°C to +125°C
Packaging: –55°C to +80°C |
| 7 |
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. |
| 8 |
Electrical specifications at 25°C. |
