■ Small air core inductors feature high Q and tight tolerance.
■ High temperature materials allow operation in ambient
temperatures up to 155°C.
■ Tin-lead (Sn-Pb) terminations ensure the best possible
board adhesion.

1. When ordering, please specify tolerance and testing codes:
MS470RAT43NGSZ
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.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
