1. When ordering, specify termination code:
SER2915-333KL
Termination: L = RoHS compliant tin-silver
over copper.
Special order:
T = RoHS tin-silver-copper
(95.5/4/0.5) or
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 or
equivalent.
3. DCR measured on a Keithley 580 micro-
ohmmeter or equivalent.
4. SRF measured using an Agilent/HP 4395A
network analyzer and an Agilent/HP 16092A
test fixture.
5. Peak dc current at which the inductance
drops the specified amount from its value
without current. When Isat rating is less than
Irms, Isat is the more critical specification.
6. Current that causes the specified tempera-
ture rise from 25°C ambient. When Irms is
greater than Isat, Isat is the more critical
specification, and Irms is shown in gray type.
See Temperature Rise vs Current curve on
next page.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount
Components” before soldering.
