Coilcraft MS450RAA272JSZ High-reliability chip inductor Datasheet

1812 CHIP INDUCTORS
High-Reliability Chip Inductors MS450RAA
■ Higher SRF values than 1812 size parts with ferrite cores
■ 2% and 1% tolerances for all values
■ 9 inductance values from 1.0 to 4.7 µH
Part number1
Inductance2
(µH)
This robust version of Coilcraft’s standard 1812CS series
features high temperature materials that allow operation
in ambient temperatures up to 155°C. The leach-resistant
base metalization with tin-lead (Sn-Pb) terminations
ensures the best possible board adhesion.

1. When ordering, please specify tolerance and testing codes:
MS450RAA333JSZ
Tolerance: F = 1% G = 2% J = 5%
Testing:
Z = COTS
H = Screening per Coilcraft CP-SA-10001
N = Screening per Coilcraft CP-SA-10003
2. Inductance measured using a Coilcraft SMD-A fixture in an Agilent/
HP 4286 impedance analyzer or equivalent with Coilcraft-provided correlation pieces.
3. Q measured at the same frequency as inductance using an Agilent/
HP 4291A with an Agilent/HP 16193 test fixture or equivalents.
4. SRF measured using an Agilent/HP 8753ES network analyzer or equivalent and a Coilcraft SMD-D test fixture.
5. DCR measured on a micro-ohmmeter.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
