1. When ordering, please specify tolerance, termination, and packaging codes:
1512SP-62NJ8EC
Tolerance: F = 1% G = 2% J = 5% K = 10% (Table shows stock tolerances in bold.)
Termination: E = Halogen free component. RoHS compliant tin-silver (96.5/3.5) over copper terminations.
Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or 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 with an Agilent/HP 4286 or equivalent, a Coilcraft SMD-A and 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 is measured on an Agilent 8753ES or equivalent with a Coilcraft CCF1268 test fixture.
6. DCR is measured on a Keithley 580 Micro-ohmmeter or equivalent.
7. Current that causes a 15°C temperature rise from 125°C ambient.
8. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components”before soldering.
