DT3316P Series

Shielded Surface Mount Power Inductors

We will continue to manufacture and support the DT3316P indefinitely, however for new designs, we recommend the MSS7341, MSS1038 or MSS1260 as alternatives. These series are more cost effective and offer better current handling.

DT3316P MSS7341 MSS1038 MSS1260

This series was always RoHS compliant; only the part numbers changed. Added characters indicate tolerance, RoHS compliance, and packaging. View old data sheet.

Notes

When ordering, please specify termination and packaging codes: e.g. DT3316P-105MLD
Inductance tested at 100 kHz, 0.1 Vrms.
DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Isat: DC current at 25°C that causes the specified inductance drop from its value without current. Temperature derating curves.
Irms: Current that causes a 10°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves.

Termination:

L = Gold over nickel over phos bronze terminations.
T = RoHS tin-silver-copper (95.5/4/0.5). (Special order, added cost)
S = non-RoHS tin-lead (63/37). (Special order, added cost)

Packaging:

D = 13″ machine-ready reel. EIA-481 embossed plastic tape (1000 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to D.
