1. When ordering, please specify packaging code:
NA5936-ALD
Packaging: D = 13machine-ready reel. EIA-481 embossed plastic tape
(800 parts per full reel).
B = Less than full reel. In tape, but not machine-ready. To
have a leader and trailer added ($25 charge), use code
letter D instead.
2. Inductance tested at 50 MHz on an Agilent/HP 4191A Impedance Analyzer
or equivalent with a Coilcraft SMD-A fixture and correlation.
3. Q tested at 50 MHz on an Agilent/HP 4291A Impedance Analyzer or
equivalent with a Coilcraft SMD-A fixture and correlation.
4. SRF tested on the Agilent/HP 8753D and a Coilcraft CCF1248 test fixture.
5. DCR tested on the Keithley 580 Micro Ohmmeter.
6. Current that causes a 15°C temperature rise from 25°C ambient.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
