SRT8045 Series Shielded
Surface Mount Power Inductors

The SRT8045 Series is not available for new designs. As an alternative, we recommend the XAL7050
Series which features soft saturation characteristics, inductance values up to 47 µH, and a smaller footprint.

For lower inductance values (0.16 µH to 10 µH), higher current ratings, and a smaller package size,
see our XAL7030 Series. For additional recommendations to optimize your design, please use our
Power Inductor Finder Tools.

  • Magnetically shielded
  • Saturation current rating up to 17.4 Amps
  • Low DC resistance for greater efficiency
  • AEC-Q200 Grade 1 (–40°C to +125°C)
  • RoHS-compliant, halogen free. 260°C compatible. RoHS compliant matte tin over nickel over phos bronze terminations
  • COTS Plus tin-silver-copper and tin-lead terminations available

1 When ordering, please specify packaging code: e.g. SRT8045-223MEC
Packaging: C = 7" reel, machine-ready EIA-481 embossed plastic tape (300 parts per full reel).
B = Less than full reel
In tape, not machine ready. To have a leader and trailer added ($25 charge), use code letter C instead.
D = 13" reel, machine-ready EIA-481 embossed plastic tape (1200 parts per full reel).
2 Inductance measured at 100 kHz, 0.1 Vrms.
3 DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
4 SRF measured using an Agilent/HP 4395A or equivalent.
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 +125°C with (40°C rise) Irms Derating curves
8 Storage temperature range: Component: −40°C to +165°C
Tape and reel packaging: −40°C to +80°C
9 Maximum part temperature: +165°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.
