High-Reliability Chip Inductors MS235RAA
Document MS198-1 Revised 06/20/11
This 0402 size chip inductor series shares all of the
characteristics of Coilcraft’s other ceramic inductors: ex-
ceptionally 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-resis-
tant base metalization with tin-lead (Sn-Pb) terminations
that ensures the best possible board adhesion.
