1. When ordering, please specify termination and packaging codes:
SLC7649S-151KLC
Termination: L = RoHS compliant matte tin over nickel over copper
Special order: T = RoHS tin-silver-copper(95.5/4/0.5) or S = non-RoHS tin-lead (63/37).
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic
tape (250 per full reel). Quantities less than full reelavailable: in tape (not machine ready) or with 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 (1000 per full reel). Factory order only, notstocked.
2. Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4263B
LCR meter or equivalent.

3. DCR is measured between the two points indicated on the dimensional
drawing.
4. SRF measured using an Agilent/HP 8753ES network analyzer orequivalent.
5. DC current at 25°C that causes a 20% (typ) inductance drop from its
value without current. Click for temperature derating information.
6. Current that causes a 40°C temperature rise from 25°C ambient. This
information is for reference only and does not represent absolute maximum ratings. Click for temperature derating information.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.

Irms Testing
Irms testing was performed on 0.75 inch wide × 0.25 inch thickcopper traces in still air.
Temperature rise is highly dependent on many factors including
pcb land pattern, trace size, and proximity to other components.
Therefore temperature rise should be verified in application
conditions.
