MS450RAB Series
High-Reliability Chip Inductors
Robust version of Coilcraft’s standard 1812LS 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.

Notes
- 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.
- Q read at test frequency directly on an Agilent/HP 4192A LF impedance analyzer and a Coilcraft SMD-B test fixture.
- SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture.
- DCR measured on a Cambridge Technology micro-ohmmeter.
