LPO4815 Series

Low Profile Surface Mount Power Inductors

Coilcraft LPO4815 Series low-profile, unshielded surface-mount power inductors offer low DC resistance and high saturation current ratings in a compact package. The low-profile ceramic case provides thermal stability and an excellent surface for pick-and-place handling.

Low profile for compact packaging
High saturation current ratings
Ceramic case for thermal stability
Ferrite core for flat L vs I curve

Notes

When ordering, please specify termination and packaging codes: e.g. LPO4815-224KLC
Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/HP 4263B LCR meter or equivalent.
DCR measured at 25°C on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
SRF measured using Agilent/HP 4191A or equivalent.
Isat: DC current at 25°C that causes a 10% (typ.) inductance drop from its value without current. Temperature derating curves
Irms: Current that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves.

Termination:

L = Silver-palladium-platinum-glass frit terminations.
T = RoHS tin-silver-copper (95.5/4/0.5). (Special order, added cost)
S = non-RoHS tin-lead (63/37). (Special order, added cost)

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).

Environmental
