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.
  • Specially designed to provide low loss benefit of ferrite and soft saturation
  • Defense Supply Center CID A-A-59406
  • RoHS-compliant. 260°C compatible. Electroplated gold (<50 µin) over nickel over phos bronze terminations
  • COTS Plus tin-silver-copper and tin-lead terminations available

1 When ordering, please specify termination and packaging codes: e.g. DT3316P-105MLD

  Termination: L = Gold over nickel over phos bronze terminations
Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) or
S
= non-RoHS tin-lead (63/37).
  Packaging: D = 13" reel, machine-ready 
EIA-481 embossed plastic tape (1000 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 100 kHz, 0.1 Vrms.
3 DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
4 Isat: DC current at 25°C that causes the specified inductance drop from its value without current.
Temperature derating curves.
5 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.
6 Ambient temperature range: −40°C to +85°C with Irms current.
7 Storage temperature range: Component: −40°C to +85°C
Tape and reel packaging: −40°C to +80°C
8 Maximum part temperature: +95°C (Ambient + temperature rise)
9 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.
10 Electrical specifications at 25°C.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
