SER2800 Series

High Current Shielded Power Inductors

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.

SER2800 Series high-current, high-inductance power inductors feature a flat-wire construction, resulting in exceptionally low DC resistance. They come in a wide range of sizes and inductance values for high current, low voltage power supplies.

Saturation current ratings up to 100 Amps
Flat wire windings provide exceptionally low DC resistance

메모

Inductance measured at 500 kHz, 0.1 Vrms, using an Agilent/HP 4284A LCR meter or equivalent.
DCR measured at 25°C on a Keithley 580 micro-ohmmeter or equivalent. For other operating temperatures, use this DCR at Temperature calculator.
SRF measured using an Agilent/HP 4395A network analyzer and an Agilent/HP 16092A test fixture. Details
Isat: DC current at 25°C that causes the specified inductance drop from its value without current. Temperature derating curves.
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.
