COILCRAFT ST450RAB

1812 CHIP INDUCTORS
Chip Inductors for Critical Applications ST450RAB
With inductance values up to 1000 µH, these are our
highest inductance chip inductors.Their ferrite core allows
higher current ratings and lower DC resistance.

2. Inductance at 2.5 MHz measured using an Agilent/HP 4286A or
equivalent and a Coilcraft SMD-A fixture with Coilcraft-provided correlation pieces. Inductance at 0.79 MHz measured using an Agilent/HP
4192A or equivalent and Coilcraft SMD-B test fixture.
3. Q read at test frequency directly on an Agilent/HP 4395A impedance
analyzer and an Agilent/HP 16193A test fixture or equivalents.
4. SRF measured using an Agilent/HP 8753D network analyzer or
equivalent and a Coilcraft SMD-D test fixture.
5. DCR measured on a Cambridge Technology micro-ohmmeter or equivalent.
6. Electrical specifications at 25°C.
