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:
XAL42±2-±±±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.
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.
2. Inductance tested at 100 kHz, 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 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.
