Notes

When ordering, please specify tolerance, termination and packaging codes: e.g. 2712SP-151J6EC
Inductance measured at 150 MHz using an Agilent/HP 4286A or equivalent with a Coilcraft SMD-A fixture and Coilcraft supplied correlation.
Tolerances in bold are stocked for immediate shipment.
Q measured at 150 MHz using an Agilent/HP 4291A with an Agilent/HP 16193A test fixture or equivalents.
SRF measured with an Agilent 8753ES network analyzer or equivalent and a Coilcraft CCF1268 test fixture. Details
DCR tested at 25°C on a Keithley 580 Micro-ohmmeter or equivalent. For other operating temperatures, use this DCR at Temperature calculator.
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.

Tolerance:

F = 1%, G = 2%, J = 5%, K = 10% (Table above shows stock tolerances in bold.)

Termination:

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)

Packaging:

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.

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.
