LPS4012 Series
Document 433-1
Document 433-1 Revised 06/08/06
This LPS4012 series of low profile
shielded power inductors is de-
signed with PDAs, wireless phones,
digital cameras and other hand-
held products in mind.
These inductors have very low DCR
and exceptional current handling ca-
pability – up to 5.0 Amps! They are
available in 30 inductance values from 0.33 µH to 3.3 mH.
Coilcraft Designer’s Kit C392 contains samples of 0.80 µH
to 33 µH parts (3 each) from LPS3008, LPS3010 and
LPS3015. Kit C401 contains samples of 0.56 µH to 33 µH
parts (3 each) from LPS4012 and LPS4018. Kit C402
contains samples of 220 µH to 3300 µH parts (3 each)
from all five series. For details of kit contents and to order,

1. When ordering, please specify packaging code:
LPS4012-682MLC
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 8753ES or equivalent.
5. For inductance values ≥10 µH, DC current at which the inductance drops
20% (max) from its value without current. For inductance values <10 µH,
DC current at which the inductance drops 30% (max) from its value
without current.
6. Storage and operating temperature range −40°C to +85°C.
7. Electrical specifications at 25°C.
