Notes
  1. When ordering, please specify termination and packaging codes: e.g. DO3340P-105MLD
  2. Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4263B LCR meter or equivalent.
  3. DCR measured at 25°C on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
  4. Isat: DC current at 25°C that causes a 10% (typ) inductance drop from its value without current. Temperature derating curves.
  5. Irms: Current that causes a 20°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 (225 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.

Soldering/Washing

Moisture Sensitivity Level (MSL):
1 (unlimited floor life at <30°C / 85% relative humidity)
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.
Refer to Soldering Coilcraft Components before soldering.
PCB Washing:
Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
