1. Please specify termination and packaging codes:
LPS4040-565MRC
2. 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.
3. DCR measured on a micro-ohmmeter.
4. SRF measured using Agilent/HP 8753ES or equivalent.
5. DC current at 25°C that causes the specified inductance drop from its
value without current.
Termination: R=RoHS compliant matte tin over nickel over silver.
Special order, added cost:
Q = RoHS tin-silver-copper (95.5/4/0.5) or P = non-
RoHS tin-lead (63/37).
Click for temperature derating information.
6. Current that causes the specified temperature rise from 25°C ambient.
This information is for reference only and does not represent absolute
maximum ratings.
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).
Click for temperature derating information.
7. Electrical specifications at 25°C.
D=13″ machine-ready reel. EIA-481 embossed plastic
tape. Factory order only, not stocked (1500 parts per
full reel).
Refer to Doc 362 “Soldering Surface Mount
Components” before soldering.
