Coilcraft Designer’s Kit C392 contains samples of 0.80 µH to 33 µH parts (3 each)
from LPS3008, LPS3010 and LPS3015. Kit C401 contains samples of 0.56 µH to
33 µH parts (3 each) from LPS4012 and LPS4018. Kit C402 contains samples of 220
µH to 3300 µH parts (3 each) from all five series. For details of kit contents and to
order, contact Coilcraft or visit http://order.coilcraft.com.
1. Please specify termination and packaging codes:
LPS4018-223MRC
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).
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 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 Compo-
nents” before soldering.
