1508/2508 Series

Low Profile Mini Spring™ Air Core Inductors

RoHS compliant AEC-Q flag
Our 1508/2508 Series low-profile Mini Spring™ air core inductors are AEC-Q200 Grade 3 (-40°C to +85°C) qualified and provide exceptionally high Q over a wide frequency range, while being less than 2/3 the height of our standard Mini Springs. Self-resonant frequencies are as high as 5 GHz in this series and they can handle as high as 4 Amps current.
  • Less than 2/3 the height of our standard Mini Spring™ parts
  • Flat top for mechanical stability and reliable pick and place operations
  • Exceptionally high Q over a wide frequency range
  • Excellent self resonance – as high as 5 GHz
  • Can handle current as high as 4 Amps
  • AEC-Q200 Grade 3 (−40°C to +85°C)

Notes
  1. When ordering, please specify tolerancetermination and packaging codes: e.g. 2508-27NJLC
  2. L and Q measured at 250 MHz, 0.1 Vrms, 0 A using an Agilent/HP 4291A impedance analyzer with an Agilent/HP 16193A test fixture.
  3. Tolerances in bold are stocked for immediate shipment.
  4. SRF measured using an Agilent/HP 8753 network analyzer and a Coilcraft SMD-D test fixture.
  5. DCR measured using a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
  6. 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:

  • = 2%, = 5% (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, 1000 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. Factory order only, not stocked, 3500 parts per full reel.
