MS235RAA Series
High-Reliability Chip Inductors
The MS235RAA Series is not recommended for new designs, but existing customers will continue to be supported. As an alternative, we recommend the AR235RAA Series which is a drop-in replacement.
This 0402 size chip inductor series shares all of the characteristics of Coilcraft’s other ceramic inductors: exceptionally high Q factors, especially at use frequencies; outstanding self-resonant frequency; tight inductance tolerance; and excellent batch-to-batch consistency.
This robust version of Coilcraft’s standard 0402CS series features high temperature materials that allow operation in ambient temperatures up to 155°C and a leach-resistant base metalization with tin-lead (Sn-Pb) terminations that ensures the best possible board adhesion.
