CTX___-__ -R(First three digits CTX; Second
2-3 digits = Inductance Value; Last 1-2 digits,
product size & type)
Product features
•
-R indicates RoHS compliant
•
Surface mount magnetics that can be used as
single or coupled inductors or 1:1 transformers
that provide isolation between two windings
OCTA-PAC’s are designed around high
frequency, low loss core material
ECONO-PAC’s are a lower cost version of OCTA-
PAC’s offering high saturation flux density, Iron
powder core material
OCTA-PAC PLUS’s offer higher current ratings
and higher saturation flux densities than OCTA-
PAC and ECONO-PAC, Amorphous metal core
material
