• Very high Q factors and excellent current handling
• Intermediate L values not found in other series
1. When ordering, please specify termination and packaging codes:
0403HQ-18N XJLW
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: W=7″ machine-ready reel. EIA-481 punched paper tape
(2000 parts per full reel).
U= Less than full reel. In tape, but not machine ready.
To have a leader and trailer added ($25 charge), use
code letter W instead.
2. Inductance measured at 500 MHz using a Coilcraft SMD-F fixture in an
Agilent/HP 4286 impedance analyzer with Coilcraft-provided correlation
pieces.
3. Q measured at 500 MHz using an Agilent/HP 4291A with an Agilent/
HP 16193 test fixture.
4. SRF measured using an Agilent/HP 8722ES network analyzer and a
test fixture with a 0.017² air gap.
5. DCR measured on a micro-ohmmeter and a Coilcraft CCF858 test
fixture.
6. Current that causes a 30°C temperature rise from 25°C ambient.
See Qualification Standards section for environmental and test data.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
Designer’s Kit C371 contains 20 of each value
Core material Ceramic
Terminations RoHS compliant silver-palladium-platinum-glass frit.
Other terminations available at additional cost.
Weight 1.29 – 1.60 mg
