Notes
- When ordering, please specify tolerance and termination codes: e.g. MS450RAA333JSZ.
- Inductance measured using a Coilcraft SMD-A fixture in an Agilent/ HP 4286 impedance analyzer or equivalent with Coilcraft-provided correlation pieces.
- Q measured at the same frequency as inductance using an Agilent/ HP 4291A with an Agilent/HP 16193 test fixture or equivalents.
- SRF measured using an Agilent/HP 8753ES network analyzer or equivalent and a Coilcraft SMD-D test fixture.
- DCR measured on a micro-ohmmeter.
Tolerance:
- G= 2%
- J = 5%
