1. When ordering, specify tolerance and testing codes:
AT394RAT10GSZ
Tolerance: G = 2% J = 5%
Testing:
Z = COTS
H = Screening per Coilcraft CP-SA-10001
N = Screening per Coilcraft CP-SA-10003
2. Inductance measured at 800 MHz on an Agilent/HP 4286A or equiva-
lent with a Coilcraft SMD-A test fixture and correlation.
3. Q measured at 800 MHz on an Agilent/HP 4291A or equivalent with a
16193A test fixture or equivalent.
4. SRF measured on an Agilent/HP 8753ES 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.
