  1. When ordering, please specify tolerancetermination and packaging codes: e.g. 2712SP-151J6EC
  2. Inductance measured at 150 MHz using an Agilent/HP 4286A or equivalent with a Coilcraft SMD-A fixture and Coilcraft supplied correlation.
  3. Tolerances in bold are stocked for immediate shipment.
  4. Q measured at 150 MHz using an Agilent/HP 4291A with an Agilent/HP 16193A test fixture or equivalents.
  5. SRF measured with an Agilent 8753ES network analyzer or equivalent and a Coilcraft CCF1268 test fixture. Details
  6. DCR tested at 25°C on a Keithley 580 Micro-ohmmeter or equivalent. For other operating temperatures, use this DCR at Temperature calculator.
  7. Irms: Current that causes a 15°C temperature rise from 125°C ambient. This information is for reference only and does not represent absolute maximum ratings.


  • = 1%, = 2%, = 5%, = 10% (Table above shows stock tolerances in bold.)


  • E = Halogen free component. RoHS compliant tin-silver (96.5/3.5) over copper terminations.
  • 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)


  • C = 7″ machine-ready reel. EIA-481 embossed plastic tape, 700 (1512SP) or 500 (2712SP) parts per full reel. Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
  • D = 13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked, 2500 (1512SP) or 2200 (2712SP) parts per full reel.
RoHS compliant , halogen free

General specification

Temperature coefficient of inductance:
+5 to +70 ppm/°C


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.
