Maxi Spring
Air Core Inductors

  • Inductance values from 90 nH to 538 nH
  • Exceptionally high Q even at low frequencies
  • Handle up to 3.5 Amps current
  • Tight tolerance can eliminate circuit tuning (tolerances as low as 2%)
  • Flat top case for mechanical stability and reliable pick and place operations
  • AEC-Q200 Grade 1 (−40°C to +125°C)
  • Solder coated leads ensure reliable soldering
  • RoHS-compliant  260°C compatible. Terminations: tin-silver over copper
  • Samples of all values are available in Coilcraft Designer's Kit C319
  • Need parts for space, military or other critical applications? See Coilcraft CPS 536RAT series.

1 When ordering, please specify tolerance, termination and packaging codes: e.g. 132-20SMJLD
Tolerance: G = 2%, J = 5% (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: D = 13″ machine-ready reel.
EIA-481 embossed plastic tape, 800 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 D instead.
2 Inductance and Q tested at 50 MHz on an Agilent/HP 4291A with a 16193 fixture using Coilcraft supplied correlation.
3 Tolerances in bold are stocked for immediate shipment.
4 SRF tested with an Agilent/HP 8753D network analyzer and a Coilcraft CCF1248 test fixture. Details
5 DCR tested at 25°C on the Cambridge Technology Model 510 Micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
6 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.
7 Ambient temperature range: −40°C to +125°C with Irms current.
8 Storage temperature range: Component: −40°C to +140°C
Tape and reel packaging: −40°C to +80°C
9 Maximum part temperature: +140°C (Ambient + temperature rise)
10 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.
11 Electrical specifications at 25°C.
12 Temperature coefficient of inductance: +5 to +70 ppm/°C.
Refer to Soldering Coilcraft Components before soldering.
