Inductance measured at 150 MHz on an Agilent/HP 4286A or equivalent with a Coilcraft SMD-A test fixture and correlation.
Q measured at 150 MHz on an Agilent/HP 4291A or equivalent with a 16193A test fixture or equivalent.
SRF measured on an Agilent/HP 8753ES or equivalent with a Coilcraft CCF1268 test fixture.
DCR measured on a Keithley 580 Micro-Ohmmeter or equivalent.
Tolerance:
G
= 2%
J
= 5%
Termination:
L
= Tin-silver over copper.
T
= Tin-silver-copper (95.5/4/0.5) over copper.
(Special order, added cost)
S
= Tin-lead (63/37) over copper.
(Special order, added cost)
Testing:
Z
= Unscreened
H
= Group A screening per Coilcraft CP-SA-10001.
All screening performed to the document’s latest revision.
Custom screening also available.
