Low Profile Chip Inductors

Our 0603CT Series low profile ceramic chip inductors are 40% lower in height than other 0603 models. Offered in a wide range of values, this series has Q factors up to 95 at 1.7 GHz and high self-resonant frequencies – up to 16 GHz.

Low profile - only 60% the height of other 0603 chip inductors
Inductance values from 1.0 to 56 nH
Exceptionally high Q – up to 95 at 1.7 GHz!
Very high self-resonant frequencies – up to 16 GHz

Notes

When ordering, specify tolerance, termination and packaging codes: 0603CT-56NXGRW
Inductance measured at 250 MHz, 0.1 Vrms, 0 Adc using Coilcraft SMDA fixture in Agilent/HP 4287A impedance analyzer
Tolerances in bold are stocked for immediate shipment.
Q measured using Agilent/HP4291A with Agilent/HP 16193 test fixture.
SRF measured using Agilent/HP 8722ES network analyzer and Coilcraft SMD -D test fixture
DCR measured on Cambridge Technology micro-ohmmeter and Coilcraft CCF858 test fixture.
Current that causes a 15°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.

Tolerance:

G=2%, J=5%

Termination:

R = RoHS compliant. Matte Sn over Ni over Ag-Pt-glass frit terminations.

T = RoHS Sn/Ag/Cu (95.5/4.0/0.5) (Special order, added cost)
S = Not RoHS Sn/Pb (63/37) (Special order, added cost)

Packaging:

W = 7″ machine-ready reel. EIA-481 punched paper tape (2000 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
U = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from U to W.
