0603 CHIP INDUCTORS
Military Grade Chip Inductors
MS312RAA
Small size, exceptional Q and high SRFs make these
inductors ideal for high frequency applications where
size is at a premium. They also have excellent DCR
and current carrying characteristics.
This robust version of Coilcraft’s standard 0603CS 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) termi-
nations that ensures the best possible board adhesion.
