Notes

Please specify termination and packaging codes: LPS4040-565MRC
Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4192A. Inductance at 1 MHz is the same for parts with SRF ≥10 MHz.
DCR measured on a micro-ohmmeter.
SRF measured using Agilent/HP 8753ES or equivalent.
DC current at 25°C that causes the specified inductance drop from its value without current. Temperature derating curves.
Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves.

Termination:

R = RoHS compliant matte tin over nickel over silver
Q = RoHS tin-silver-copper (95.5/4/0.5) (Special order, added cost)
P = non-RoHS tin-lead (63/37) (Special order, added cost)

Packaging:

C = 7″ machine-ready reel. EIA-481 embossed plastic tape (500 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
D = 13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (1500 parts per full reel).
