1. Please specify
termination
and
packaging
codes:
LPS4012-225MRC
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).
Packaging: C
= 7″ machine-ready reel. EIA-481
embossed plastic tape (1000 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 (3500 parts
per full reel).
B
= Less than full reel. In an effort to
simplify our part numbering system,
Coilcraft is eliminating the need for
multiple packaging codes. When
ordering, simply change the last
letter of your part number from B to C.
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 induc-
tance drop from its value without current.
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.
Click for temperature derating information.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components”
before soldering.
