0906/1606 Series

Micro Spring™ Air Core Inductors

RoHS compliant AEC-Q flag
Our 0906/1606 Series Micro Spring™ 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 their high Q and the lowest possible losses for high-frequency applications. High-reliability versions are available for space, military, and other critical applications.
 
  • Inductance values from 1.65 nH to 12.55 nH (tolerances as low as 1%)
  • Tight tolerance can eliminate circuit tuning
  • Flat top for mechanical stability and reliable pick and place operations
  • Exceptionally high Q over a wide frequency range
  • Very high self resonance (up to 10 GHz)
  • Solder coated leads ensure reliable soldering
  • AEC-Q200 Grade 1 (−40°C to +125°C)

Notes
  1. When ordering, please specify tolerancetermination and packaging codes: e.g. 1606-10JLC
  2. Inductance measured at 800 MHz using an Agilent/HP 4286A or equivalent with a Coilcraft SMD-A fixture and correlation.
  3. Tolerances in bold are stocked for immediate shipment
  4. Q measured at 800 MHz using an Agilent/HP 4291A with an Agilent/HP 16193A test fixture or equivalents.
  5. SRF measured with an Agilent/HP 8720D network analyzer or equivalent and a Coilcraft SMD-D test fixture.Details
  6. DCR tested at 25°C on a Cambridge Technology Model 510 Micro-ohmmeter or equivalent. For other operating temperatures, use this DCR at Temperature calculator
  7. 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.

Tolerance:

  • = 1%, = 2%, = 5%, = 10% (Table above shows stock tolerances in bold.)

Termination:

  • L = 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)

Packaging:

  • C = 7″ machine-ready reel. EIA-481 embossed plastic tape, 500 parts per full reel. Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
  • 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.
  • P = 7″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (3000 parts per full reel).
