1. When ordering, please specify packaging code:
Packaging:

4310LC-352KEC
C = 7″ machine-ready reel. EIA-481 embossed plastic
tape (350 parts per full reel). Quantities less thanfull reel available: in tape (not machine ready) orwith leader and trailer ($25 charge).
B = Less than full reel. In an effort to simplify our partnumbering system, Coilcraft is eliminating the needfor multiple packaging codes. When ordering, simply
change the last letter of your part number from B to C.
D = 13″ machine-ready reel. EIA-481 embossed plastictape. Factory order only, not stocked (1500 parts perfull reel).

2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/HP16193 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.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
