1. When ordering, please specify termination and packaging code:
SLC7649S-101KLC
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 = 7machine-ready reel. EIA-481 embossed plastic
tape (250 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 = 13machine-ready reel. EIA-481 embossed plastic
tape (1000 per full reel). Factory order only, not
stocked.
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 dimen-
sional drawing.
4. SRF measured using an Agilent/HP 8753ES network analyzer or
equivalent.
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.
• Designed for use in multi-phaseVRM/VRD regulators and high
current/high frequency DC/DC converters.
• Requires only 60 mm2 of board space; can handle up to 100 A
