1008HT (2520)

Low Profile Chip Inductors

With a maximum height of only 0.045 inches, our 1008HT Series has the lowest profile of all our 1008-sized chip inductors. Available in a wide range of standard values, these inductors have exceptionally high Q vs non-wirewound inductors of the same size. Ceramic construction assures the highest possible self-resonant frequencies – up to 7.9 GHz.

Our lowest profile 1008 chip inductors – only 0.045" high!
Inductance values from 3.3 nH to 560 nH (tolerances as low as 1%)
Exceptionally high Q compared to non-wirewound inductors, especially at high frequencies
Ceramic construction for highest possible self resonance (up to 7900 MHz)
Excellent current carrying capacity for their size

Notes

When ordering, please specify tolerance, termination and packaging codes: e.g. 1008HT-R56TGRC
Inductance measured using a Coilcraft SMD-A fixture in an Agilent/ HP 4286A impedance analyzer with Coilcraft-provided correlation pieces.
Tolerances in bold are stocked for immediate shipment.
Q measured using an Agilent/HP 4291A with an Agilent/HP 16193 test fixture.
SRF measured using an Agilent/HP 8720D network analyzer and a Coilcraft SMD-D test fixture.
DCR measured on a Cambridge Technology micro-ohmmeter and a Coilcraft CCF840 test fixture. For other operating temperatures, use this DCR at Temperature calculator.
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:

F = 1%, G = 2%, J = 5% (Table above shows stock tolerances in bold.)

Termination:

R = RoHS compliant matte tin over nickel over silver platinum-glass frit.
L = RoHS compliant silver-palladium-platinum-glass frit.
T = RoHS tin-silver-copper (95.5/4/0.5) (Special order, added cost)
S = non-RoHS tin-lead (63/37) (Special order, added cost)

Packaging:

C = 7″ machine-ready reel. EIA-481 embossed plastic tape (2000 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
D = 13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (7500 parts per full reel).
B = 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 B to C.
