1. When ordering, please specify **termination** and **packaging** codes: 

## **XFL4015-122MEC** 

**Termination: E** = RoHS compliant tin-silver 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 (1000 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge). 

   - **B** = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is elimnating the need for 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 (4000 parts per full reel). 

## **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. 

2. Inductance tested at 1 MHz, 0.1 Vrms, 0 Adc. 

3. DCR measured on a micro-ohmmeter. 

4. SRF measured using Agilent/HP 4395A 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. 

7. Electrical specifications at 25°C. 

Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
