1. When ordering, specify termination code:
SER2915-333KL
Termination: L = RoHS compliant tin-silvercopper over copper.
E= Halogen free component.
RoHS compliant tin-silverover copper.
Special order:
S = non-RoHS tin-lead(63/37).
2. Inductance measured at 500 kHz, 0.1 Vrms,
0 Adc on an Agilent/HP 4284A LCR meter orequivalent.
3. DCR measured on a Keithley 580 microohmmeter or equivalent.
4. SRF measured using an Agilent/HP 4395A
network analyzer and an Agilent/HP 16092A
test fixture.
5. DC current at 25°C that causes the specified
inductance drop from its value without current.
Click for temperature derating information.
When Isat rating is less than Irms, Isat is themore critical specification.
6. Current that causes the specified temperature rise from 25°C ambient. This information
is for reference only and does not represent
absolute maximum ratings.
Click for temperature derating information.
When Irms is greater than Isat, Isat is
the more critical specification, and Irms isshown in gray type. See Temperature Rise vsCurrent curve on next page.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount
Components” before soldering.
