1. When ordering, please specify

tolerance and testing codes:

ML450RAA333JLZ

Tolerance:

F = 1% G = 2% J = 5%

Testing:

Z = COTS

H = Screening per Coilcraft CP-SA-10001

N = Screening per Coilcraft CP-SA-10003

2. Inductance measured using a Coilcraft SMD-A fixture in an Agilent/

HP 4286 impedance analyzer or equivalent with Coilcraft-provided correla-

tion pieces.

3. Q measured at the same frequency as inductance using an Agilent/

HP 4291A with an Agilent/HP 16197 test fixture or equivalents.

4. SRF measured using an Agilent/HP 8753ES network analyzer or equiva-

lent and a Coilcraft SMD-D test fixture.

5. DCR measured on a Keithley 580 micro-ohmmeter or equivalent and a

Coilcraft CCF859 test fixture.

6. Electrical specifications at 25°C.
