1111SQ Series

Square Air Core Inductors

RoHS-konform Halogenfrei
Coilcraft 1111SQ Series square air core inductors have extremely high Q factors and very tight inductance tolerances, making them suitable for narrowband RF amplifier matching and tuning applications. As their name implies, air-core inductors do not use a magnetic core, resulting in high Q and the lowest possible losses for high-frequency applications. High-reliability versions are available for space, military, and other critical applications.
  • Exceptionally high Q – up to 200 at 400 MHz
  • Inductance values from 27 to 47 nH
  • Flat top and bottom for reliable pick and place and mechanical stability
  • Solder coated leads ensure excellent solderability
  • For lower inductance values, consider the 0806SQ, 0807SQ and 0908SQ
  • For higher inductance values, consider the 1515SQ, 2222SQ and 2929SQ

Hinweise
  1. When ordering, please specify tolerancetermination and packaging codes: e.g. 2929SQ-501JEC
  2. Inductance measured at specified test frequency, 0.1 Vrms, 0 A using an Agilent/HP 4286A LCR meter with a Coilcraft CCF1191C test fixture.
  3. Tolerances in bold are stocked for immediate shipment
  4. Q measured at specified test frequency, using an Agilent/HP 4291A impedance analyzer.
  5. SRF measured using an Agilent/HP 8753 network analyzer and a Coilcraft CCF1248 test fixture.
  6. DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
  7. Irms: Current that causes a 20°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.

Toleranz:

  • = 2%, = 5% (Table shows stock tolerances in bold.)

Anschlüsse:

  • E = RoHS compliant tin-silver (96.5/3.5) over copper.
  • T = RoHS tin-silver-copper (95.5/4/0.5) over copper. (Special order, added cost) 
  • S = non-RoHS tin-lead (63/37) over copper. (Special order, added cost) 

Verpackung:

  • C = 7″ machine-ready reel.
    EIA-481 embossed plastic tape  (600 parts per full reel).
  • B = Less than full reel. In tape, but not machine-ready.
    To have a leader and trailer added ($25 charge), use code letter C instead.
  • D = 13″ machine-ready reel. EIA-481 embossed plastic tape (2500 parts per full reel). Factory order only, not stocked.
