SER2800 Series High Current
Shielded Power Inductors

For new designs, consider the new SER2900 series. This new series offers the same high current handling and excellent DCR as the SER2800 and has a  third mounting pad that makes it suitable for a much wider range of applications. We will continue to manufacture and support the SER2800 indefinitely.
  • Designed for high current, low voltage power supplies
  • Saturation current ratings up to 100 Amps
  • Flat wire windings provide exceptionally low DC resistance
  • RoHS-compliant. 260°C compatible. Tin-silver over copper terminations.

1 Inductance measured at 500 kHz, 0.1 Vrms, using an Agilent/HP 4284A LCR meter or equivalent.
2 DCR measured at 25°C on a Keithley 580 micro-ohmmeter or equivalent.For other operating temperatures, use this DCR at Temperature calculator.
3 SRF measured using an Agilent/HP 4395A network analyzer and an Agilent/HP 16092A test fixture. Details
4 Isat: DC current at 25°C that causes the specified inductance drop from its value without current.
Temperature derating curves.
5 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.
6 Ambient temperature range: −40°C to +85°C with (40°C rise) Irms Derating curves
7 Storage temperature range: Component: −40°C to +125°C
Packaging trays: −40°C to +80°C
8 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.
9 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.
