0603CHIPINDUCTORS
OutgassingCompliantChipInductors AS312RAA
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
90
features high temperature materials that pass NASA low
80
outgassing specifications and allows operation in ambient
70
temperatures up to 155°C. The leach-resistant base
60
metalization with tin-lead (Sn-Pb) terminations ensures
the best possible board adhesion.
