1 When ordering, please specify tolerance, termination and packaging codes: e.g. 2712SP-151NJ6EC
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.
Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5)
S = non-RoHS tin-lead (63/37).
  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.
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 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
8 Ambient temperature range: −40°C to +125°C with Irms current.
9 Storage temperature range: Component: −40°C to +140°C
Tape and reel packaging: −40°C to +80°C
10 Maximum part temperature: +140°C (Ambient + temperature rise)
11 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.
12 Electrical specifications at 25°C.
Refer to Soldering Coilcraft Components before soldering.
