CHIP INDUCTORS
GENERAL
RoHS
2002/95/EC
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.
