Shielded Power Inductors – XAL1030
• Very high current and low DCR
• Low profile, only 3 mm high
• Soft saturation makes them ideal for VRM/VRD applications.

Testing
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:
XAL1030-102MEC
C
= 7″ machine-ready reel. EIA-481 embossed plastic tape (250 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 (1000 parts per full reel).
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 which the inductance drops 30% (typ) amount from its value without current.
6. Current that causes the specified temperature rise from 25°C ambient.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
