1008HQ (2520) High Q
Ceramic Chip Inductors

  • Very high Q factors – far higher than non-wirewound types.
  • Inductance values from 3 nH to 100 nH (tolerances as low as 1%)
  • Ceramic construction for highest possible self resonance - up to 8.1 GHz
  • Excellent current carrying capacity for their size
  • Defense Supply Center CID A-A-59739
  • RoHS-compliant  260°C compatible. Silver-palladium-platinum-glass frit terminations
  • COTS Plus tin-silver-copper and tin-lead terminations available
  • Samples of all values available in Coilcraft Designer's Kit C323
  • Need parts for space, military or other critical applications? See Coilcraft CPS 413RAD series.

1 When ordering, please specify tolerance, termination and packaging codes: e.g. 1008HQ-R10XGLC
Tolerance: F = 1%, G = 2%, J = 5% (Table above shows stock tolerances in bold.)
Termination: L = RoHS compliant silver-palladium-platinum-glass frit
R = RoHS compliant matte tin over nickel over silver-platinum-glass frit.
Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) or
S
= non-RoHS tin-lead (63/37).
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" reel, machine-ready 
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.
2 Part is wound on a low profile coilform.
3 Inductance measured at 50 MHz using a Coilcraft SMD-A fixture in an Agilent/HP 4286A impedance analyzer with Coilcraft-provided correlation pieces.
4 Tolerances in bold are stocked for immediate shipment.
5 Q measured using an Agilent/HP 4291A with an Agilent/HP 16193 test fixture.
6 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  an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture. Details
7 DCR measured at 25°C on a Cambridge Technology Micro-ohmmeter and a Coilcraft CCF840 test fixture. For other operating temperatures, use this DCR at Temperature calculator.
8 Irms: 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.
9 Ambient temperature range: −40°C to +125°C with Irms current.
10 Storage temperature range: Component: −40°C to +140°C
Tape and reel packaging: −40°C to +80°C
11 Maximum part temperature: +140°C (Ambient + temperature rise)
12 Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
13 Electrical specifications at 25°C.
14 Temperature coefficient of inductance (TCL): +25 to +125 ppm/°C.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested with pure water or alcohol only. Other solvents.
