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.

1. When ordering, please specify termination and testing codes:
ST450RAB105JLZ
Termination: L = RoHS compliant silver-palladium-platinum glass frit.
Special order:
R = Tin over nickel over silver-platinum-glass frit.
S = Tin-lead (63/37) over silver-platinum-glass frit.
T = Tin-silver-copper (95.5/4/0.5) over silver-platinum-
glass frit.
P = Tin-lead (63/37) over tin over nickel over silver-plati-
num-glass frit.
Q = Tin-silver-copper (95.5/4/0.5) over tin over nickel
over silver-platinum-glass frit.
Testing: Z = COTS
H = Screening per Coilcraft CP‑SA‑10001
2. Inductance at 2.5 MHz measured using an Agilent/HP 4286A or
equivalent and a Coilcraft SMD-A fixture with Coilcraft-provided cor-
relation 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.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
