DS3316P Series

Shielded Surface Mount Power Inductors

We will continue to manufacture and support the DS3316P indefinitely, however for new designs, we recommend the MSS1038 as an alternative. The MSS1038 is more cost effective, features a smaller footprint, lower profile, lower DCR and better current handling.

Notes

When ordering, please specify termination and packaging codes: e.g. DS3316P-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 a 10% (typ) inductance drop from its value without current.
Temperature derating curves.
Irms: Current that causes a 40°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.
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.
