  • Ultra small wirewound inductor – 20% smaller than our 0402CS
  • 45 inductance values from 0.67 to 100 nH
  • Exceptionally high Q – up to 131 at 2.4 GHz!
  • Very high self-resonant frequencies

Notes
  1. When ordering, please specify termination and packaging codes: e.g. 0302CS-101XJRW
  2. Inductance measured at 250 MHz using a Coilcraft SMD-F fixture in an Agilent/HP 4286 impedance analyzer with Coilcraft-provided correlation pieces.
  3. Q measured using an Agilent/HP 4287A with an Agilent/HP 16193 test fixture
  4. SRF measured using an Agilent/HP 8722ES network analyzer and a test fixture with a 0.017" air gap.
  5. DCR measured at 25°C on a micro-ohmmeter and a Coilcraft CCF858 test fixture. For other operating temperatures, use this DCR at Temperature calculator.
  6. Irms: Current that causes a 30°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.

Termination:

  • R = RoHS compliant. Matte Sn over Ni over Ag-Pt-glass frit terminations.

Packaging:

  • W = 7" machine-ready reel
    EIA-481 punched paper tape (2000 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
  • U = 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 U to W.

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.
