1. When ordering, please specify termination and testing codes:
ML450RAB105JLZ
Termination: L = RoHS compliant silver-palladium-platinum glass frit.
Special order:
R = Tin over nickel over silver-platinum-glass frit.
Testing: Z = COTS
H = Screening per Coilcraft CP-SA-10001
N = Screening per Coilcraft CP-SA-10003
2. Inductance at 2.5 MHz measured using an Agilent/HP 4286A and
a Coilcraft SMD-A fixture with Coilcraft-provided correlation pieces.
Inductance at 0.79 MHz measured using an Agilent/HP 4192A and
Coilcraft SMD-B test fixture.
3. Q read at test frequency directly on an Agilent/HP 4192A LF impedance
analyzer and a Coilcraft SMD-B test fixture.
4. SRF measured using an Agilent/HP 8753D network analyzer and a
Coilcraft SMD-D test fixture.
5. DCR measured on a Cambridge Technology micro-ohmmeter.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
