Designer’s Kit C418 contains 3 each of all values
Core material Ferrite
Terminations RoHS compliant matte tin over nickel over phos
bronze. Other terminations available at additional cost.
Weight: 2.8 g – 3.3 g
Ambient temperature –40°C to +125°C with
Irms current, +125°C
to +165°C with derated current
Storage temperature Component: –40°C to +165°C.
Packaging: –40°C to +80°C
Resistance to soldering heat Max three 40 second reflows at
+260°C, parts cooled to room temperature between cycles
Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C /
85% relative humidity)
Failures in Time (FIT) / Mean Time Between Failures (MTBF)
38 per billion hours / 26,315,789 hours, calculated per Telcordia SR-332
Packaging 500/13
″ reel; Plastic tape: 24 mm wide, 0.35 mm thick,
16 mm pocket spacing, 6.6 mm pocket depth
PCB washing Only pure water or alcohol recommended
• Designed for high ambient temperatures – 125°C
• Very low DCR, excellent current handling
• Magnetic shielding allows high density mounting.
1. Please specify termination and packaging codes:
MSS1260T-105K
LD
Termination: L = RoHS compliant matte tin over nickel
over phos bronze.
Special order:
T = RoHS tin-silver-copper (95.5/4/0.5)
or S = non-RoHS tin-lead (63/37).
Packaging: D =13
″ machine-ready reel.
EIA-481 embossed plastic tape
(500 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 D
instead.
2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc
using an Agilent/HP 4263B LCR meter or
equivalent.
3. DCR measured on a micro-ohmmeter and a
Coilcraft CCF858 test fixture.
4. SRF measured using an Agilent/HP 8753D network
analyzer and a Coilcraft SMD-D test fixture.
5. DC current at which the inductance drops the
specified amount 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 Compo-
nents” before soldering.
