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.
