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.
1. When ordering, please specify termination and packaging codes:
SLC1049-151MLC
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
dimensional diagram.
4. SRF measured with coils connected in series using an Agilent/HP
8753ES network analyzer or equivalent.
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 reel
available: in tape (not machine ready) or with leader
and trailer ($25 charge).
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 maxi-
mum ratings. Click for temperature derating information.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
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 (1000 per full reel). Factory order only, not
stocked.
