SMT Power Inductors – DO3316T
• Designed for high temperature applications – over 125°C
ambient
• AEC-Q200 qualified; ideal for many automotive applications
• Soldered self-leaded construction for excellent solderability
• 10% tolerance for most values
• Low DCR and high current handling
Designer’s Kit C396
contains 3 of each 20% value
Core material
Ferrite
Core and winding loss
See www.coilcraft.com/coreloss
Terminations
RoHS compliant tin-silver-copper over copper. Other
terminations available at additional cost.
Weight
0.95 – 1.25 g
Ambient temperature
–40°C to +155°C. See derating curve for
Irms
vs Temperature.
Storage temperature
Component: –40°C to +155°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
750/13″ reel Plastic tape: 24 mm wide, 0.35 mm thick,
12 mm pocket spacing, 6.4 mm pocket depth
PCB washing
Tested with pure water or alcohol only. For other solvents,
see Doc787_PCB_Washing.pdf.
1. When ordering, specify
tolerance, termination
and
packaging
codes:
DO3316T-474MLD
Tolerance: M =
20%,
K
= 10% (Table shows stock tolerances in bold.)
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 (750 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 C instead.
2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc.
3. Tolerances in bold are stocked for immediate shipment.
4. SRF measured using Agilent/HP 8753D network analyzer.
5. DC current at which the inductance drops 10% (typ) from its value with-
out current.
6. Current that causes a 40°C temperature rise from 25°C ambient.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
