1. Please specify
termination
and
packaging
codes:
LPS4012-682MLC
Termination: L
= RoHS compliant silver-palladium-
platinum-glass frit.
Special order:
T
= RoHS tin-silver-copper (95.5/4/0.5)
or
S
= non-RoHS tin-lead (63/37).
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 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 that causes the specified inductance drop
from its value without current.
6. Current that causes the specified temperature rise
from 25°C ambient.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components”
before soldering.
