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.
