Notes
  1. When ordering, please specify tolerance and packaging cods: e.g. DO3316T-474MLD
  2. Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4263B LCR meter or equivalent.
  3. Tolerances in bold are stocked for immediate shipment.
  4. DCR measured at 25°C on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
  5. SRF measured using an Agilent/HP 8753D network analyzer. Details
  6. Isat: DC current at 25°C that causes a 10% (typ) inductance drop from its value without current. Temperature derating curves.
  7. 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.

Tolerance:

  • M = 20%, K = 10% (Table above shows stock tolerances in bold.)

Termination:

  • RoHS compliant tin-silver-copper over copper. Other terminations available at additional cost.

Packaging:

  • 13" reel, machine-ready 
    EIA-481 embossed plastic tape (750 parts per full reel).
  • B = Less than full reel 
    In tape, not machine ready. To have a leader and trailer added ($25 charge), use code letter D instead.

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.
