Notes
  1. When ordering, please specify termination and packaging codes: e.g. 4310LC-132KEC
  2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/HP 16193 fixture in Agilent/HP 4284A impedance analyzer or equivalent.
  3. ​SRF measured using Agilent/HP 8753D network analyzer or equivalent and a Coilcraft SMD-F test fixture.
  4. DCR measured at 25°C on a Keithley 580 micro-ohmmeter or equivalent. For other operating temperatures, use this DCR at Temperature calculator.
  5. Irms: Current that causes the specified temperature rise from 25°C ambient. Because of their open construction, these parts will not saturate. This information is for reference only and does not represent absolute maximum ratings.

Termination:

  • E = RoHS compliant tin-silver over copper.
  • 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:

  • C = 7" machine-ready reel
    EIA-481 embossed plastic tape (350 parts 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 C instead.
  • 13" reel, machine-ready
    EIA-481 embossed plastic tape. Factory order only, not stocked (1500 parts per full reel).

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.
