1. When ordering, please specify termination and packaging codes:
1812LS-105XJLC
Termination: L = RoHS compliant silver-palladium-platinum-glass frit.
Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or
S = non-RoHS tin-lead (63/37).
2. Inductance at 2.5 MHz measured using an Agilent/HP 4286A and a
Coilcraft SMD-A fixture with Coilcraft-provided correlation pieces.
Inductance at 0.79 MHz measured using an Agilent/HP 4192A and
Coilcraft SMD-B test fixture.
3. Q read at test frequency directly on an Agilent/HP 4192A LF impedance
analyzer and a Coilcraft SMD-B test fixture.
4. SRF measured using an Agilent/HP 8753D network analyzer and a
Coilcraft SMD-D test fixture.
5. DCR measured on a Cambridge Technology micro-ohmmeter.
6. Current that causes a 15°C temperature rise from 25°C ambient.
Because of their open construction, these parts will not saturate.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
See Color Coding section for part marking data.
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic
tape (600 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 (2200 per full
reel).
Specifications subject to change without notice.
