SMT Power Inductors - LPO4815 Series
LPO4815 power inductors share the
same footprint as our LPO4812 series
(4,6 x 4,8 mm), but their 0,3 mm extra
height allows them to handle up to
35% more current. A rugged ceramic
case completely protects the winding
and provides an ideal surface for pick
and place handling.
The small footprint and high efficiency of the LPO4815
make this series well suited for battery powered equip-
ment like cameras, phones, PDAs and other handheld
devices.

1. When ordering, please specify
packaging
code:
LPO4815-224KXC
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 (3500 parts per full reel).
2. Inductance tested at 100 kHz, 0.1 Vrms.
3. DCR measured on a micro-ohmmeter.
4. SRF measured using Agilent/HP 4191A or equivalent.
5. DC current at which the inductance drops 10% (typ) from its value
without current.
6. Average current for a 40°C temperature rise from 25°C ambient.
7. Operating and storage temperature range
−40°C
to +85°C.
8. Electrical specifications at 25°C.
See Qualification Standards section for environmental and test data.
