Mini Spring
Air Core Inductors

  • Inductance values from 2.5 nH to 43 nH (tolerances as low as 2%)
  • Tight tolerance can eliminate circuit tuning
  • Flat top jacket for mechanical stability and reliable pick and place operations
  • AEC-Q200 Grade 1 (−40°C to +125°C)
  • Exceptionally high Q over a wide frequency range
  • Highest possible self resonance (greater than 3 GHz)
  • Solder coated leads ensure reliable soldering
  • RoHS-compliant  260°C compatible. Terminations: tin-silver over copper
  • COTS Plus tin-silver-copper and tin-lead terminations available
  • Samples of all values are available in Coilcraft Designer's Kit C302
  • Need parts for space, military or other critical applications? See Coilcraft CPS 439/470RAT series.

1 When ordering, please specify tolerance, termination and packaging codes: e.g. B10TJLC
Tolerance: F = 1%, G = 2%, J = 5%, K = 10% (Table above shows stock tolerances in bold.)
  Termination: L = RoHS compliant tin-silver (96.5/3.5) over copper.
Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) over copper or
S = non-RoHS tin-lead (63/37) over copper.
  Packaging: C = 7" machine-ready reel.
EIA-481 embossed plastic tape, 700 (AxxT) or 500 (BxxT) 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, 2500 (AxxT) or 2200 (BxxT) parts per full reel.
2 Inductance measured at 150 MHz using an Agilent/HP 4286A or equivalent with a Coilcraft SMD-A fixture and Coilcraft supplied correlation.
3 Tolerances in bold are stocked for immediate shipment.
4 Q measured at 150 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 the 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.
8 Ambient temperature range: −40°C to +125°C with Irms current.
9 Storage temperature range: Component: −40°C to +140°C
Tape and reel packaging: −40°C to +80°C
10 Maximum part temperature: +140°C (Ambient + temperature rise)
11 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.
12 Electrical specifications at 25°C.
13 Temperature coefficient of inductance: +5 to +70 ppm/°C.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
