SMT Power Inductors – DS3316P Series
Magnetic shielding and high efficiency are features of
the DS3316 family of power inductors. They are de-
signed for high performance DC-DC converter applica-
tions, especially those requiring shielding.
The terminations wrap around the end of the base,
ensuring a sound solder fillet and simplifying inspection.
Saturation current ratings up to 11 A and rms current
ratings as high as 5 A are available. DC resistance as
low as 0.021 Ohms keeps power losses to a minimum.
For new designs, consider the MSS1038 as an alter-
native to this series. The MSS1038 series is more cost
effective, features a smaller footprint, lower profile, lower
DCR and better current handling. We will continue to
manufacture and support the DS3316 indefinitely.

1. When ordering, please specify
termination
and
packaging
codes:
DS3316P-105MLD
Termination: L
= RoHS compliant gold over nickel over phos bronze.
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 (1000 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 D instead.
2. Inductance tested at 0.1 Vrms, 100 kHz, 0 Adc.
3. DC current at which the inductance drops 10% (typ) from its value
without current.
4. Current that causes a 40°C temperature rise from 25°C ambient.
5.
Ambient temperature range:
–40°C to +85°C with
Irms
current
+85°C to +125°C with derated current
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.
See Qualification Standards section for environmental and test data.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
