2. Inductance measured at 150 MHz on an Agilent/HP 4286A or equivalent with
a Coilcraft SMD-A test fixture and correlation.
3. Q measured at 150 MHz on an Agilent/HP 4291A or equivalent with a 16193A
test fixture or equivalent.
4. SRF measured on an Agilent/HP 8753ES network analyzer or equivalent
with a Coilcraft CCF1268 test fixture. Parts with SRF >5 GHz are verified to
>5 GHz in screening
5. DCR measured on a Keithley 580 Micro-Ohmmeter or equivalent.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
