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). 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 (2500 parts per full reel). Factory order only, not stocked.
  • 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.
