SER1390 Series High Current
Shielded Power Inductors

  • Saturation current ratings up to 13.2 Amps
  • Exceptionally low DC resistance
  • RoHS-compliant. 260°C compatible. Matte tin over nickel over phos bronze.
  • For lower inductance values, consider the shorter SER1360 series.
  • COTS Plus tin-silver-copper over copper and tin-lead terminations available
  • Need parts for space, military or other critical applications? See Coilcraft CPS 615PTA series.

1 When ordering, please specify termination and packaging codes: e.g. SER1390-473MLD
  Termination: L = RoHS compliant matte tin over nickel over phos bronze.
Special order, added cost: T = RoHS tin-silver-copper over copper (95.5/4/0.5) or
S = non-RoHS tin-lead (63/37).


D = 13" machine-ready reel
EIA-481 embossed plastic tape (300 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 D.
2 Inductance measured at 100 kHz, 0.1 Vrms, using an Agilent/HP 4284A or equivalent.
3 DCR measured at 25°C on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
4 SRF measured using an Agilent/HP 4395A network analyzer and an Agilent/HP 16193A test fixture. Details
5 Isat: DC current at 25°C that causes the specified inductance drop from its value without current.
Temperature derating curves.
6 Irms: Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Temperature derating curves.
7 Ambient temperature range: −40°C to +85°C with (40°C rise) Irms Derating curves
8 Storage temperature range: Component: −40°C to +125°C
Tape and reel packaging: −40°C to +80°C
9 Maximum part temperature: +125°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.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
