## **Irms Testing** 

I rms testing was performed on 0.75 inch wide × 0.25 inch thick copper 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. 

1. When ordering, please specify **termination** and **packaging** codes: | ~~———_~~ 

**SLC1049-151MLC** 

- **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). 

   - **B** = 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. 

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. 

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 maximum ratings. Click for temperature derating information. 

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 (1000 per full reel). Factory order only, not stocked.
