1. When ordering, please specify termination and packaging codes:
SLC7530S-101MLC
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 (500 parts 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 = 13″ machine-ready reel. EIA-481 embossed plastic
tape. Factory order only, not stocked (1700 parts per
full reel).

2. Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4263B LCR
meter or equivalent.
3. DCR is measured on a micro-ohmmeter at points indicated in the diagram.
Points used for measur
ing DCR
4. SRF measured using an Agilent/HP 8753ES network analyzer and a
Coilcraft SMD-D fixture.
5. DC current at which the inductance drops 20% (typ) from its value with-
out current.
6. Current that causes a 40°C rise from 25°C ambient.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
Designer’s Kit C379 contains 3 each of all values.
Core material Ferrite
Core and winding loss See www.coilcraft.com/coreloss
Terminations RoHS compliant matte tin over nickel over copper.
Other terminations available at additional cost.
Weight: 0.44 – 0.47 g
Ambient temperature –40°C to +85°C with Irms current, +85°C to
