0402 CHIP INDUCTORS
Military Grade Chip Inductors
MS235RAA
This 0402 size chip inductor series shares all of the charac-
teristics 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-resis-
tant base metalization with tin-lead (Sn-Pb) terminations
that ensures the best possible board adhesion.
