0603 CHIP INDUCTORS
High-ReliabilityChipInductors ML312RAA
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.
