1. When ordering, please specify packaging code:
SLC1175-301MEC
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic
tape (150 per full reel). Quantities less than full reelavailable: in tape (not machine ready) or with leader
and trailer ($25 charge).
B = In an effort to simplify our part numbering system,
Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the lastletter of your part number from B to C.
D = 13″ machine-ready reel. EIA-481 embossed plastictape. 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.

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 absolutemaximum ratings. Click for temperature derating information.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.

Irms Testing
Irms testing was performed on 0.75 inch wide × 0.25 inch thickcopper traces in still air.
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.
