1. When ordering, please specify tolerance and testing codes:
ML470RAT43NGLZ
Tolerance: G = 2%â 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.
Refer to Doc 362 âSoldering Surface Mount Componentsâ before soldering.
