1. When ordering, please specify termination and packaging codes:
XFL5018-332MEC
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 andtrailer ($25 charge).
D = 13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked(XFL5015: 4000 parts per full reel, XFL5018: 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 an inductance drop of 30% (typ) 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 onlyand 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.

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 factorsincluding pcb land pattern, trace
size, and proximity to other components. Therefore temperaturerise should be verified in application conditions.
