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.

1. When ordering, please specify packaging code:
XAL52±2-±±±MEC
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 100 kHz, 0.1 Vrms, 0 Adc.
3. DCR measured on a micro-ohmmeter.
4. SRF measured using an Agilent/HP 4395A or equivalent.
5. DC current at which the inductance drops 30% from its value without
current.
6. Current that causes the specified temperature rise from 25°C ambient.
7. Electrical specifications at 25°C.
