SMT Power Inductors

DT3316P Series
These magnetically shielded inductors are designed for
a wide variety of applications, including board mounted
DC-DC converters, miniature power supplies and volt-
age multiplying circuits. They function equally well in
filter and smoothing circuit applications.
The Coilcraft DT Series is specially designed to provide
the low-loss benefit of ferrite, with a soft saturation
characteristic, allowing best performance at both light
load and high peak current conditions.
For new designs, consider the MSS7341, MSS1038
or MSS1260 as alternatives to this series. These
series are more cost effective and offer better current
handling. In addition, the MSS7341 is a significantly
smaller part. We will continue to manufacture and sup-
port the DT3316P indefinitely.

1. When ordering, please specify termination and packaging codes:
3. DC current at which the inductance drops from its value without current.
4. Current that causes a 10°C temperature rise from 25°C ambient.
DT3316P-125MLD
5. Ambient temperature range:
–
40°C to +85°C with Irms current
+85°C to +95°C with derated current
6. Storage temperature range: Component: 40°C to +85°C
Packaging: 40°C to +80°C
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).

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
temperaturebetween.
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.
8. Electrical specifications at 25°C.
See Qualification Standards section for environmental and test data.
See Color Coding section for part marking information.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
2. Inductance tested at 0.1 Vrms, 100 kHz, 0 Adc.
Specifications subject to change without notice.
