1. When ordering, please specify termination and packaging codes:
IrmsTesting
Irms 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 com-
ponents. Therefore temperature
rise should be verified in appli-
cation conditions.
XFL42±2-47±MEC
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).
B = Less than full reel. In tape, but not machine ready. To have a leader and trailer added
($25 charge), use code letter C instead.
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.
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.
