Shielded Power Inductors
–
XAL7020
• High current and very low DCR
• Soft saturation makes them ideal for VRM/VRD applications.
Designer’s Kit C45± contains 3 of each value.
Core material Composite
Environment RoHS compliant, halogen free
Terminations RoHS compliant tin-silver (96.5/3.5) over copper. Other
terminations available at additional cost.
Weight 0.83 g
Ambient temperature –40°C to +125°C with Irms current, +125°C to
+165°C with derated current.

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:
XAL72±2-±±±MEC
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic tape (500 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
(2000 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 Agilent/HP 4395A or equivalent.
5. DC current at which the inductance drops 30% (typ) 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.
