Chip Inductors
–
1008CT Series (2520)
The 0.055″ profile makes these parts ideal for low
clearance applications. Their simple construction en-
sures high reliability and stability, and they feature much
higher SRF values than ferrite alternatives. For free

1. When ordering, specify tolerance, termination and packaging codes:
1008CT-101XJLC
Core material Ceramic
Terminations RoHS compliant silver-palladium-platinum-glass frit.
Other terminations available at additional cost.
Tolerance: F = 1% G = 2% J = 5%
Weight 17.8 – 17.8 mg
(Table shows stock tolerances in bold.)
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).
Ambient temperature –40°C to +125°C with Irms current, +125°C
to +140°C with derated current
Storage temperature Component: –40°C to +140°C.
Packaging: –40°C to +80°C
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic
tape (2000 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.
Resistance to soldering heat Max three 40 second reflows at
+260°C, parts cooled to room temperature between cycles
Temperature Coefficient of Inductance (TCL) +25 to +125 ppm/°C
D = 13″ machine-ready reel. EIA-481 embossed plastic
tape (7500 parts per full reel).
Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C /
85% relative humidity)
2. Inductance measured using a Coilcraft SMD-A fixture in an Agilent/HP
4286A impedance analyzer with Coilcraft-provided correlation pieces.
3. Tolerances in bold are stocked for immediate shipment.
4. Q measured at using an Agilent/HP 4291A with an Agilent/HP 16193 test
fixture.
5. SRF measured using an Agilent/HP 8720D network analyzer and a
Coilcraft SMD-D test fixture.
Failures in Time (FIT) / Mean Time Between Failures (MTBF)
One per billion hours / one billion hours, calculated per Telcordia SR-332
Packaging 2000/7″reel; 7500/13″ reel Plastic tape: 8 mm wide,
0.3 mm thick, 4 mm pocket spacing, 1.6 mm pocket depth
PCB washing Only pure water or alcohol recommended
6. DCR measured on a Cambridge Technology micro-ohmmeter and a
Coilcraft CCF840 test fixture.
7. Current that causes a 15°C temperature rise from 25°C ambient.
8. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
Specifications subject to change without notice.
