Notes

When ordering, specify termination code: e.g. SER2915-333KL
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. When Irms is greater than Isat,Isat is the more critical specification and Irms is shown in gray type. See temperature rise vs Current.

Termination:

L = RoHS compliant tin-silver-copper over copper.
E = Halogen free component. RoHS compliant tin-silver over copper.
S = non-RoHS tin-lead (63/37). (Special order)
