Shielded Power Inductors – XPL4020
• Excellent current handling, low DCR and soft saturation
makes them ideal for VRM/VRD applications
• Large terminations provide low resistance, excellent ther-
mal management and the best possible board adhesion
Designer’s Kit C432
contains 3 each of all values
Terminations
RoHS compliant matte tin over nickel over copper.
Other terminations available at additional cost.
Weight
0.16 g – 0.18 g
Ambient temperature
–40°C to +125°C. The part can be operated
without damage as long as the part (ambient temperature plus
temperature rise due to self heating) does not exceed +165°C.
Storage temperature
Component: –40°C to +165°C.
Packaging: –40°C to +80°C
Resistance to soldering heat
Max three 40 second reflows at
+260°C, parts cooled to room temperature between cycles
Moisture Sensitivity Level (MSL)
1 (unlimited floor life at <30°C /
85% relative humidity)
Failures in Time (FIT) / Mean Time Between Failures (MTBF)
38 per billion hours / 26,315,789 hours, calculated per Telcordia SR-332
Packaging

1. When ordering, please specify
packaging
code:
XPL4020-103MLC
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 Agilent/HP 4395A or equivalent.
5. DC current at which the inductance drops the specified
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.

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 components. Therefore temperature rise should
be verified in application conditions.
Specifications subject to change without notice.
