Chip Inductors – 0402PA (1005)
With current ratings as high as 1.8 A, Coilcraft’s 0402PA
wirewound chip inductors are ideal for power amplifiers
in TDMA, CDMA, GSM and other wireless applications.
Compared to our standard 0402CS Series, they can
handle up to 65% more current and have half the DC
resistance.These inductors are perfect for use as an RF
choke for the power supply, the LC tank between ampli-
fier and antenna and in the amplifier bias circuit. Like our
other ceramic chip inductors, they feature outstanding self-
resonant frequencies and excellent Q values. Most values
are available in 2% inductance tolerance.
Coilcraft Designer’s Kit C373 contains samples of all 5%
inductance tolerance parts. To order, contact Coilcraft or

1. When ordering, specify tolerance, termination and packaging codes:
Tolerance: G = 2% J = 5%
Termination: E = Halogen free component. RoHS compliant silver-
palladium-platinum-glass frit terminations.
L = RoHS compliant, not halogen-free. Silver-palladium-
platinum-glass frit terminations.
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 250 MHz using a Coilcraft SMD-F test fixture
and Coilcraft-provided correlation pieces with an Agilent/HP 4286 imped-
3. Tolerances in bold are stocked for immediate shipment.
4. Q measured using an Agilent/HP 4291A with an Agilent/HP 16193 test
5. For SRF >6 GHz, measured using an Agilent/HP 8722ES network
analyzer and a Coilcraft SMD‑D test fixture. For SRF £6 GHz, measured
using anAgilent/HP 8753D network analyzer and a Coilcraft SMD‑D test
6. DCR measured on a micro-ohmmeter.
