1. When ordering, please specify packaging code:
SLR1190-371KECPackaging: C = 7″ machine-ready reel. EIA-481 embossed plastic
tape (100 parts per full reel). Quantities less thanfull reel available: in tape (not machine ready) orwith leader and trailer ($25 charge).
B = Less than full reel. In an effort to simplify our partnumbering system, Coilcraft is eliminating the needfor 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. Factory order only, not stocked (450 parts perfull reel).
2. Inductance at 100 kHz, 0.1 Vrms, 0 Adc.
3. DCR is measured on a micro-ohmmeter at points indicated in thediagram below.

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.

4. DC current that causes a 20% (typ) inductance drop from its value
without current. Click for temperature derating information.
5. 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.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
