Notes

When ordering, please specify termination code: e.g. SER3018H-333KE
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 16193A 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.

Termination:

E= Halogen free component. RoHS compliant matte tin over nickel over phos bronz.
T = RoHS tin-silver-copper over copper(95.5/4/0.5). (Special order)
S = non-RoHS tin-lead (63/37). (Special order)
