1. When ordering, please specify termination and packaging codes:
XEL3515-561MEC
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 ($25charge).		
B = Less than full reel. 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 ofyour part number from B to C.		D = 13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked(3500 parts per full reel).
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.
6. Current that causes the specified temperature rise from 25°C ambient. This information is for reference onlyand does not represent absolute maximum ratings.
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 toother components. Therefore
temperature rise should beverified in application conditions.
