1. When ordering, please specify packaging code:
4310LC-132KEC
2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/HP
16193 fixture in Agilent/HP 4284A impedance analyzer. or equivalents.
3. SRF measured using Agilent/HP 8753D network analyzer or equivalent
and a Coilcraft SMD-F test fixture.
4. DCR measured on Keithley 580 micro-ohmmeter or equivalent.
5. Current that causes the specified temperature rise from 25°C ambient.
Because of their open construction, these parts will not saturate.
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic
tape (350 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 C instead.
D = 13″ machine-ready reel. EIA-481 embossed plastic
tape. Factory order only, not stocked (1500 parts per
full reel).
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
