1. When ordering, please specify packaging code:
SLC1175-301MEC
4. SRF measured using an Agilent/HP 8753ES network analyzer or equivalent.
5. DC current at 25°C that causes the specified inductance drop from its
value without current. Click for temperature derating information.
6. Current that causes the specified temperature rise from 25°C ambient.
This information is for reference only and does not represent absolute
maximum ratings. Click for temperature derating information.
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic
tape (150 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.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
D = 13″ machine-ready reel. EIA-481 embossed plastic
tape. Factory order only, not stocked (700 per full reel).
2. Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4284.
3. DCR is measured between the two points indicated below.
