CHIP INDUCTORS
GENERAL
Coiltronics 1210 Series Chip Inductors are ideally suited
for signal and moderate power circuit SMT applications.
Both the CTX32 and CTX32C Product Families are
designed to provide superior reliability due to their rugged
ceramic case construction. Precise manufacturing
processes provide mechanically sound devices which
maintain tolerance specifications. The devices are
supplied in 8 mm tape and reel packaging which facilities
automatic assembly insertion.
Coiltronics designs and manufactures many standard and
custom electro-magnetic components. Contact the factory
or your nearest Coiltronics representative or distributor
with your transformer and inductor requirements.
