For new designs, consider the 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.

  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
