1. When ordering, please specify packaging code:
2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/
HP 4284A impedance analyzer.
3. SRF measured using Agilent/HP 8753D network analyzer and Coilcraft
SMD-D test fixture.
4 DC current at which the inductance drops the specified amount from its
value without current.
5. Current that causes the specified temperature rise from 25°C ambient.
This information is for reference only and does not represent absolute
maximum ratings. Click for temperature derating information.
SD43-683KLC
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic
tape (500 parts per full reel). Quantities less than full
reel available: in tape (not machine ready) or with
leader and trailer ($25 charge).
B = Less than full reel. In an effort to simplify our part
numbering system, Coilcraft is eliminating the need
for 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 plastic
tape. Factory order only, not stocked (2000 parts
per full reel).
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
