1. When ordering, please specify tolerance and testing codes:
AT470RAT43NGSZ
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 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.
